I have caffeine pills, 100mg each. They have lost there kick with me even though I am only taking 1-2 a day and following the directions of spacing them out by atleast 3 hours.
I am doing fasted cardio each morning and my plan is to take 1 pill in the morning and thats it but I am thinking about increasing it to 2 pills. Would this be a good or bad idea? the only negative side effects I am get off caffeine is dry retching, and heartburn(hence the no 2nd dose).
