Coffee and caffeine cause bipolar depression, by dehydrating the body, causing adrenal fatigue, sleep deprivation, extreme mood swings, extreme ups and downs, anxiety and racing thoughts and prevents you from absorbing vitamins and nutrients from your food. Caffeine stays in your sytem for over 24 hours and prevents you from entering REM sleep so you never receive restful sleep if you are a coffee drinker. If you suffer from depression, you need to ween yourself off of coffee and all caffeine immediately.
You will get 8 hours of deep restful REM sleep by day 4 after completely eliminating caffeine.
