Keep a full water bottle on your desk at all times — visible = consumed
Drink 500ml immediately upon waking (your body is dehydrated after 8h of no water)
Set a hourly phone reminder — when it goes off, drink 250ml before doing anything else
Use a marked water bottle with time goals (8am, 10am, 12pm...) — gamification works
Replace one non-water drink per day with water — soda, juice, energy drink → water
Eat water-rich foods: cucumber (95%), watermelon (91%), oranges (87%), yogurt (85%)
Carbonated water with lemon/lime if you hate plain water — it's still water
Drink a full glass before every meal (this also reduces calorie intake 10-15%)
