Re: Amantadine for opiate tol. reversal Hi catpoo, You have a pretty sharp GP, Oxy and morphine are different classes of opiates, One being synthetic and morphine being an opium akaloy or opioid rather than an opiate. This is some of the WORST advice I have ever heard. Both benzos and opiates are EXTREMELY addictive - the only catch, BENZO withdrawal can KILL whereas opiate withdrawal, while nasty, is rarely life-threatening. Doxepin also may potentiate the adverse effects of anticholinergic agents such as benztropine, atropine and hyoscine (scopolamine). Tolazamide , when used in conjunction with doxepin has been associated with a case of severe hypoglycaemia in a type II diabetic individual. [21] I have never used doxepin to potentiate opiates or benzos. This kid who used to give me shitloads of ritalin and dexies once found some in his mums medicine cabinet and we took one each one morning before snorting ritalin at recess.

I want to feel relaxed yet energized, like how Opiates make you feel. I was hoping that, since I can't really feel my Sub anymore (been on it about 5 months now) the Gabapentin and/or the Seroquel would maybe potentiate or synergise nicely with the Sub to bring on a buzzed feeling. It's an Rx antihistamine. it does potentiate the sedating effects of opiates as well as help with the itch. I couldn't quantify how much more intense opiates are with hydroxyzine. Have you used Benadryl to potentiate? It would be similar to that. Also, be careful if your tolerance is low. My oral surgeon uses hydroxyzine to potentiate oxycodone, which makes for a nice combination. In contrast, I never take the more easily available diphenhydramine to amp up opiates. I find hydroxyzine preferable to diphenhydramine when used as a sleep aide. I have never used doxepin to potentiate opiates or benzos.
