don't go cold turkey. I know from experience. Try weaning yourself with smaller and less cups a day. Always have water on you. Try prayer for self control to help you get past the urge to drink more coffee
How do I give up caffeine addiction?
Caffeine-containing beverages like coffee and tea are mildly diuretic, making it necessary to drink more water to replace what is excreted. There is just no substitute for that precious liquid, water.
Tips for Increasing Water Intake
● Carry a water bottle.
● Drink a glass with every meal.
● Drink before, during, and after exercise.
● Take water breaks instead of coffee breaks.
● To improve the taste of tap water, add lemon juice or use a filter.
Wean off slowly is the easiest method. Cut your consumption a little bit at a time, to allow your body to adjust.
