How much Benadryl?
I weigh over 150lbs, and i am having a severely hard time falling asleep and staying asleep. I want to know how many 25mg of diphenhydramine capsules will help me get very sleepy? and how much is too much? normally when i take them for allergies i take 2, but they never make me sleepy. i think i have a slight immunity to it. please help?
