A heroin comedown? What's that? And how would anybody believe that a meth comedown isn't as bad as a heroin comedown? Heroin "comedowns" are just feeling kinda itchy and tired and a little nauseous sometimes. Meth keeps you up forEVER and you physically and mentally just feel like shit. even if you only do a single dose, the comedown is much worse than any opiate crash. i've ever had.
Anyway to answer your original question, I would tell you that you shouldn't take meth, but realistically, i know you're gonna do it regardless, so I might as well te you how to be as safe as possible with it:
I'd take it orally, maybe 30-50mg depending on the quality, and 30 minutes before taking it, take 300mg chelated magnesium (an essential supplement for any amphetamine use), which will help with any jaw tenion, as well as a number of other things, like tolerance, muscle tightness, anxiety, etc. i'd reccomend starting at 20mg just to test the quality, and f you don't feel strong effects starting effects within an hour, titrate your dose up as needed until you're where you want to be, but try not exceed 50mg if possible. After reaching your "sweet spot", DO NOT REDOSE; redosing leads to all the negative effects meth is associated with, like psychosis, paranoia, and lots of other horrible stuff, but oral meth lasts a very long time, so you shouldn't feel the need to redose anyway.
If you choose to snort, the above all applies, but tbh, oral is not only safer, but its 2-3 times longer lasting than snorting, produces very strong euphoria almost as strong as snorted meth, and has very little comedown compared to other ROAs and most other stimulants in general IME.
Also, keep a benzo on hand in case anything starts to get out of control. And make sure to eat, drink water, take a multivitamin, and get as much sleep as possible after you come down.
