I usually only mix the two when I’m in the middle of a cycle and get woke up due to hits. When this happens, I also get hit thru the day and count on energy shots to keep the hit at bay or at least tame them down. Due to the overload of caffeine, and need to sleep, I take 50mg of Benadryl and 20mg melatonin at night before going to bed. It usually does a good job keeping hits at bay.
I’m sure it is not the most healthy way to go, but in the middle of a cycle a guy has got to do what you can to keep going. I certainly would not recommend it to anybody without consulting your doctor. I gradually up the doses until I found what works for me.
