I just really hope the information I share can help somebody to save their health and set them free. And I am very grateful to you for the kind words of appreciation - that's a kind of dopamine and serotonin boost those poor people we are talking about don't receive often if ever!

Let me also give credits: portions of this information (e.g about need in big doses of vitamins A&E, about supplementing dopa/tyrosine while on meth being a bad idea (though good during the abstinence, together with tryptophan) and that you really must drink a huge lot of water on meth, e.g. 1-2 full glasses every time you pee - this will actually save your kidneys, not overload them) come from Quora and Reddit, others from Adam at PsychedSubstance on YouTube (see https://www.youtube.com/watch?v=FlMxTpONKT0 - every advice from this video on MDMA applies to meth too), others from Wikipedia (e.g. about magnesium and emoxypine), some from my own reasoning and experimentation and the whole journey to understanding addictions has began with this extremely true video https://www.youtube.com/watch?v=ao8L-0nSYzg I have also tried everything on myself (many years ago, I have only met the person who given me the substance once while dead drunk at a club, can't remember his face, I don't have his number and I don't know where to get meth at all, believe it or not this is true) as well as just meth without the supplements so I could compare and confirm everything (that's not nearly as credible as a good double-blind placebo-controlled test could be but I personally have no doubts, especially in piracetam which is not FDA-approved unfortunately yet extremely effective and safe in big doses as my experience suggests). I am not a doctor, however, and can be wrong in some parts yet I believe no of my advises can harm more than just taking meth without following them (unless the patient happens to be allergic to a particular supplement or something like that).

BTW, regarding the "invite him to spend a meth-free weekend at your house" part - be really careful doing this with people you don't know well, some real junkies (I haven't met any but have heard scary rumors, these were more about crack an heroine addicts, not meth, but people are different and some can be more madness-prone than others) can happen to be really dangerous, especially when they go crazy on the drug/withdrawal-induced paranoia. Make sure to keep your wife and children away, knives, guns, jewelry and windows well-locked and have a beefy buddy by your side for just a case - "better safe than sorry".

And an addition about magnesium: don't use mg lactate with meth, I don't know the details but I've heard they don't fit together, prefer a chelate, oxide or citrate.

Another might-be-important thing I've forgotten to mention is supplementing pro&pre-biotics: meth-induced diarrhea can harm intestinal ecology seriously and a recent study I've read about in New Scientist says the major portion of all body serotonin (which is crucial for emotional well-being and also affected by meth) is produced in the intestines, not in the brain.

PS: I'm not on meth writing this much :-) Just too much coffee, "the stairs effect", urge to procrastinate and enthusiasm to help people by sharing understanding :-)
