Nmda antagonism only.keeps tolerance at bay, and does not decrease tolerance. I'm not saying you said that, I was pointing it out
Well at those doses dxm has minimal nmda blocking efficiency and thus is not.the best choice, but it will do the trick. Try addjng in magnesium supplements for extra benefits.
You are taking a low dose and you shouldn't have withdrawal, maybe a slight snri discontinuation syndrome which is what the pharm companies say instead of wd. But it really shouldn't be that bad for you.
It would be a good idea to take a break often especially if you take.dxm in the form of syrups because the dyea and sugars in them are not good for your digestive system Nd liver.
You'll be fine. I would rotate on and off every other 2 weeks. Like do 2 weeks then stop for 1-2 weeks, ect...
I actually found taking a second plateau or high first plateau dose 12-24 hrs before I took my oxy or heroin worked the best. Like 200-300mgs a good 6 or 8 or 12 hours before, and on the comedown take I'd takebthe opiate and the sensation was.spectacular
