Reversing opiate/ opioid tolerance

There is a trick that may well restore your tolerance by resetting the NMDA receptors - a low dose non-competitive NMDA antagonist. Memantine is the best for this purpose because it has a long half life and unlike DXM, it doesn't have a lot of interactions and it doesn't get you high. It reverses tolerance to just about anything you abstain from for a month or so. I was on it for two weeks before it bottomed out my alcohol tolerance so much that I drank one beer at a friend's house when I was doing my bankruptcy and I got a euphoric buzz from it whereas my normal alcohol tolerance is so high that I need a twelve pack in a two hour period or so to catch a decent buzz.
