I once, almost ODd... I don't know how. I believe it was a poor reaction I had to a medication I was on at the time, in combination with a massive dose of meth -- something that's never happened before hit me. My pulse dropped, I got weak and started feeling like I was literally about to start spasming or go into convulsions at any second. Kept getting these odd waves of "chills" almost going through me, that made me literally like panic for a second thinking "it's happening this time, this time it won't pass..." It's hard to describe. Then I got muscle aches as though I had spent half the day in the gym and slightly torn them from overuse, you know.It's never fully gone away. This was a month or two ago, and I still get flashes of that odd sick state even though I stopped the medication I think had caused it. Very troublesome. Worries me, but... what'm I gonna do, if I'm damaged and don't heal, that fucking sucks. But it's done.Apparently that may have been rhabdomyolisis (muscle cells breaking down and flooding toxins into my blood stream due to severe metabolic... something, I don't remember... acidosis maybe? Whatever).I'm no doctor though, and supposedly if that really is what was happening to me, I'm damn lucky my kidneys still work at all. But anyway, other than in combination with other substances, it's *extremely* difficult to overdose on methamphetamine. Not to say it's extremely hard to have a bad time, just extremely hard to outright kill yourself from overdosing on them. They can very easily trigger a preexisting condition that makes you unusually susceptible to something like cardiac arrest, or a section of an artery or vein close to your brain (or in your brain) that's genetically weak for whatever reason could burst (a stroke), that sort of thing. But if you look it up, some estimates of the LD50 are literally 90mg/kg. If you weigh an average-ish 80kg, that's 7.2grams. That's a fucking quarter ounce of meth. Over $500 worth, and more than you could swallow in one go, so... yeah. True overdosing is very hard. Going too far and not enjoying yourself is much easier.
