i think it would be safe i've done both it would prolly jsut be a crzy trip look for trip reports on erowid for people that have done both at once
187 Reviewed by 187 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
