Right, I have used diphenhydramine a few times, though not lots of it. onyl around 250mg or so, and has had very some mildish trips on it - vision distortions, things like posters appear to be moving and my bedspread moving like an ocean wave. could have been a bit more than 250mg but thats it approximetly. Anyway I want to try DXM and I am looking for something a bit more intense than what I have already had on diphenhydramine so far. So... I have found the only product he can seem to locally which is Benylin Non Drowsy Dry Cough, which unfortunatly onyl has 220mg of DXM per bottle in it. So how much do you suggest? I have tripped on other substances other than diphenhydramine before, so I amn't worried about not knowing what its like. thankyou in advance.
