well, lately Ive been dosing DXM (like 30mg) about an hour before I use IV heroin to try and prevent any tolerance from gaining. I also have been drinking grapefruit juice for potentiation. I know long-term it can build up, but it doesnt potentiate it much and whatever helps I guess. Now, I know grapefruit juice also potentiates benzo's. I was wondering if the NMDA antagonist effects of DXM had any ill side-effects with benzo's? As well as diphenhydramine and melatonin, which I take pretty often at night to help me sleep. Thanks.
