I've quit drinking coffee two weeks ago. I felt really numb for 8 days, and then I started to just feel normal again. Before I drank way too much coffee. Now I don't know what to do, if I want to drink a little bit of tea every day or if I want to use caffeine just on an occasional basis trying to avoid any dependency. For now I'll stick to 0 caffeine for a little longer and see how I feel. But I'd be curious to know other peoples experiences or advice.
