dude really dont do it... ive heard storeis where people take both and end up going to the hospital to get their stomach pumped and just dont take the chance... just do 400 more mg of dxm and you wont need the benadryl
ibreakthings Reviewed by ibreakthings on . Combining DXM and Benadryl I know this can be dangerous.. but would 300 mg of just DXM and 300 mg of just diphenhydramine be a safe combination? I've tripped on 754 mg of DXM alone before and 400 mg of diphenhydramine alone before. Rating: 5
