I Quit Sugar for 90 Days. Here's My Honest Diary (Including the Part Where I Cried Over Tim Tams)
The Short Version
Quitting added sugar for 90 days was brutal — especially days 3–7 (flu-like withdrawal). By week 4 cravings vanished. I lost 8.1kg, fixed energy crashes, and reset my taste buds. Morning moringa smoothie + protein at every meal made it survivable. Jump to hell week.
- ✓ 8.1kg lost
- ✓ Brain fog gone
- ✓ Zero daily cravings by day 90
Okay, This Is Gonna Be Brutally Honest
Every "I quit sugar!" blog makes it sound like you become a zen goddess who floats through life craving kale. That's horseshit.
Quitting sugar was one of the hardest things I've done — harder than quitting smoking. I failed twice before it stuck.
This is my actual diary. The good days, the terrible days, the day I almost punched a coworker for eating a muffin near me, and the day I cried in the Coles car park because I couldn't buy chocolate.
Nobody tells you: how terrible days 3–7 are, that sugar is in everything "healthy," why your brain screams at 3pm, or how awkward social situations get.
Why I Decided to Quit (The Breaking Point)
December 28, 2025. Third Magnum of the day. Earlier: Tim Tams, vanilla slice, "healthy" acai bowl (~35g sugar), afternoon chocolate bar. ~150–200g sugar (limit is <25g/day). I barely tasted the third ice cream — it was automatic.
I was chemically addicted. Couldn't go a day without it, thought about it constantly, ate when stressed, felt awful after, kept going anyway.
Plus: exhausted, brain fog, mood swings, +5kg in 4 months, adult acne, always bloated.
January 1st, I'm quitting. (Not Dec 29th. Christmas leftovers first.)
My 90-day transformation (day 90)
The Rules I Set
NO: added sugar, honey/maple/agave, dried fruit, juice, soft drinks (even diet — sweeteners keep cravings), anything >5g sugar per 100g.
YES: whole fruit (max 2/day), vegetables, protein, fats, unsweetened carbs (rice, bread, potatoes).
Motivation: photo on fridge, "90 DAYS" on calendar, told three friends.
Days 1–2: The Honeymoon (This Is Easy!)
Day 1 Easy
Eggs and avocado breakfast. Black coffee + almond milk. 3pm: almonds instead of chocolate — proud. Dinner stir-fry: learned soy sauce has sugar, switched to tamari. "Why did everyone say this was hard?"
Day 2 Harder
Smoothie (banana, berries, protein). 3pm craving was rough — apple was not chocolate. Friends got dessert; I got peppermint tea. Felt boring.
Days 3–7: Hell Week (Oh My God Make It Stop)
This is the part nobody warns you about. Legitimately one of the worst weeks of my life.
Day 3 Hell
Flu-like: throbbing headache, exhausted, brain fog, irritable. Stared at office birthday cake for two minutes. Almost quit. Googled "day 4 quitting sugar" — forums said push through.
Day 4 Scary
Worse. Nausea + headache. Called in sick. Nearly drove to Coles for chocolate. What stopped me: thousands of others saying days 3–7 are the worst.
Day 5 Angry
Headache easing. Microwaved fish in the office? Wanted to scream. Sugar withdrawal drops serotonin — you're just cranky.
Day 6 Better
Woke without alarm. One coffee enough. Walked past vending machine. Friend brought wine + chocolate — said no to chocolate, she thought I was insane.
Day 7 Turning point
Felt… normal. Cravings eased. Down 1.8kg in one week from sugar alone. That was enough to keep going.
Survival tips for hell week
- Sleep as much as you can
- Water — 3–4 litres daily
- Eat when hungry — don't restrict calories too hard
- Be gentle with yourself
DO NOT QUIT during this week. If you push through, it gets so much better.
Weeks 2–8: Getting Easier → Transformation
Week 2: Stable energy, better sleep, skin clearing, bloating down. Cravings manageable. Social awkwardness at morning tea. -2.9kg total.
Week 3 — hidden sugars: Kombucha (15g), protein bars (18–25g), granola, flavored yogurt, sauces, acai bowls (30–40g). I was eating "healthy" and still hitting 80–100g/day.
Week 4: Walked past chocolate aisle — felt nothing. Brain dopamine reset. Fruit tasted insanely sweet. -4.2kg.
Weeks 5–6: No more 7am zombie / 3pm crash rollercoaster. Stable energy 7am–10pm. -5.5kg.
Weeks 7–8: No exercise change — still walking 3–4×/week. -6.4kg, waist -7cm, face slimmer, bloating gone.
Weeks 9–12: The New Normal
Birthday party: one bite of cake — too sweet, didn't want more. Energy, sleep, clear skin. Day 90 targets: -7.2kg, waist -9cm, cravings basically zero.
Day 90 — April 1st, 2026
Final: -8.1kg · waist -11cm · stable energy · best sleep in years · clear skin · calm mood.
Going back to daily sugar? No. Not a diet — I just don't want it. Special occasions: dessert is fine. Daily: fruit or 85% dark chocolate if I want sweet.
It's preference, not willpower.
The Science (Why This Happens)
Your gut bacteria cause cravings
Bad bacteria feed on sugar and signal your brain for more. When you quit, they starve (weeks 1–2 = withdrawal), good bacteria grow, cravings fade.
I used: probiotic 50B CFU, moringa + sauerkraut (prebiotics), fermented foods.
Willpower doesn't beat biology
Blood sugar drops → cortisol → anxiety → brain demands sugar. Fix: protein every meal (30g+), healthy fats, fiber, don't skip meals.
What Actually Helped
1. Moringa smoothie every morning
Satisfied sweet craving, stable energy, full until lunch. ~$0.80/smoothie vs $18 café acai bowl. NutriThrive Moringa — $11/100g
2. 30g protein minimum per meal
Eggs, Greek yogurt, chicken, salmon, tuna — rarely hungry between meals.
3. Herbal tea at 3pm
Peppermint, rooibos, licorice root, cinnamon — instead of chocolate.
4. "Boring food" strategy
Same breakfast smoothie daily, simple lunches — less food-as-entertainment = fewer cravings.
5. Planned social situations
Ate before events, brought snacks, herbal tea at cafés, "no thanks, I'm good" without long explanations.

FAQs
Can I have fruit?
Yes — fiber slows absorption. Limit 1–2 pieces/day month one, then as you like.
What about honey?
No for 90 days. Still spikes blood sugar.
Diet soft drinks?
No first 90 days — artificial sweeteners keep cravings alive.
Alcohol?
Dry wine/spirits okay occasionally. Skip sweet cocktails and beer early on.
How much weight will I lose?
Varies. I lost 8.1kg. Many lose 3–7kg month one, then 0.5–1kg/week.
Cheat days?
Not first 30 days — one cheat can reset cravings to day 1.
The Bottom Line
Days 3–7 were terrible. I almost quit. It was worth it: 8.1kg, stable energy, amazing sleep, clear skin, no addiction.
Week 1 = hell. Weeks 2–3 = hard. Week 4+ = magic. Fix your gut, stabilize blood sugar, cravings disappear.
It's biology, not willpower. Start tomorrow. Track progress. You've got this.
