Due to my health issue, I will stop drinking coffee, I have hypertension and insomnia the doctor said to much drink of caffeine may trigger my illness. I admit that my day is not complete if i didnt smell or taste the coffee it makes me more energize and boost my mood and also my stress relliever most of the time I drink atleast 3 to 4x a day. I try to replace healthy drink 3 days ago after my consultation. Is there any cause in my mood and health when I do coffee withdrawal?
