I have a bottle of Diphenhydramine HCL 25mg. My question is: can I trip or get some kind of high from taking this? If so, how much would I have to take? I know it's not safe and the drug is sold as a sleep aid and not meant for this, but I kinda want to give it a try if it will get me high. So...will it? And how much would I have to take for it to do so....and to NOT overdose?
