No trouble sleeping on Speed

So I just got Speed for the first time. I washed it with Atceton, dried it etc. But when I snort it, even big lines, I got no trouble sleeping 3 hours later and even eating is no problem. Dont get me wrong I still get some effects like a bit euphoria and feeling awake, but even that stops after an hour and I feel like I can easily go to sleep. I did Coke a couple times and there I had even trouble sleeping 6-8 hours after the last line. But there a was on a rave every time and did Molly too, so I dont know if it can be compared. Now I take it to study for my engineering exams and I dont feel like it changes a lot. Does it just mean that the Speed I got is shit? Couse I washed it and the reviews on the DN Vendor for this Speed were very good and also the ones that were just a couple days old. Should I maybe take it in a capsule?

Thanks to everyone who read this🤝
