by the way, it's diphenhydramine hcl that you're looking for, NOT benadryl. benadryl has it in it, but unless you want to pay over 5x as much as you could for a generic brand with the same ingredient, might want to get the diphen instead. can be found in many sleep-aid medications along with several allergy meds. people just won't let the stupid "benadryl" recommendation die .
