Yeah, you took dosages that are what I personally would consider to be way too high. I have taken this much before, but I had a very similar experience. Prior to having a prescription and thus medical advice on adderall dosage (that admittedly I don't always follow precisely as I take it when I need it rather than everyday), my dealer who sold me the pills in college told me to take similar amounts to this. And my experience was no fun, to say the least. And pretty much exactly the same. Don't take anymore adderall, as it will only exacerbate the problem and worsen the ensuing crash even more. I don't use adderall recreationally. I use it to improve my overall functioning, and I only typically take 20 or perhaps 30 milligrams of adderall at the most, though even the 30 mg gives me a bit of a crash at times when I do that. If I take more than that, I find that the effect on my performance doesn't improve but unfortunately the side effects do. If you overdo it with adderall, simply getting good sleep, eating well, and staying hydrated as well as NEVER taking more adderall if you are crashing like this will ensure that you won't have any serious issues IMO. The problems of adderall (or any stimulant) is primarily sleep deprivation, which is cumulative. So, if you keep taking it and taking it and becoming sleep deprived, you'll have problems. If you stop taking adderall and rest along with getting hydrated and drinking enough fluids, you'll be okay I think.
I'm crashing from a different stimulant and feeling similar to you. I also have had little sleep. The stim I took was an RC that's extremely similar to meth. I also did take my adderall today, after I felt a bit "tired" after crashing when I woke up from the other stuff. So, it's quite a similar situation. I feel somewhat better now, though I have had some alcohol (doesn't exactly do anything for you physically but takes your mind off a crummy feeling crash like I have). Unfortunately, I'll say that this RC that I took sucks and is best avoided as my "high" was merely being hyperactive and very irritable. Last time I took it, it was good....... this time it wasn't. I haven't slept much lately as I did psychedelics as well the night prior to doing this. So, I have only had like a few hours of sleep for several nights kind of like this...... and a ton of stuff in my system. It fucking sucks right now though, but the whole stimulant crash is kind of like gravity IMO. It happens for EVERYONE who overdoes it, every single person....... and what goes up must come down. So, the more you take and the greater the high, the greater the crash. I will admit that I really do admit that this pharmacological "gravity" of sorts didn't exist....... as then one could enjoy the ups without the downs. But unfortunately it doesn't work that way. And IME and from everyone I know who also takes stims either for fun or to improve performance, if you take ANY more stims while crashing, it is a VICIOUS cycle. The next crash is worse than the first one and so on...... leading to crappy, substandard "ups" and even more miserable and fucked up "downs" than ever. Stimulants have negative side effects, but fortunately the negative effects are very predictable.
I'm sure I'll be fine as well, but the whole RC thing is a little weird for me TBH 8( I'm assuming that said RC follows the same physical laws so to speak as regular amphs. Yet this crash does really fucking suck. Probably just paranoid and still tweaking a bit, but still I definitely either will never take this stuff again or will take in the AM when I am able to get a good sleep. Because taking this shit too late in the day is only trouble. Same for the OP with the adderall, the dose at 5:30 PM was very late in the day, and it makes sense that you didn't sleep at all last night. Taking an XR of 45 mg at 5:30 basically gurantees little to no sleep for anyone. All in all, I enjoy stims....... yet at the same time I find them a rather crappy substance. I know that seems contradictory, but that's just the nature of the beast it seems from my experience and other folks I like who take them.
