I took 50 mg of adderall but I took the powder out of the pill and just threw it in my mouth. I took it at midnight and it is 2:30 PM, so I pulled an all nighter. I have been awake for a total of 28 hours and can't sleep. I also haven't eaten anything but a handful of frosted flakes in 25 hours but I'm not hungry at all. Does this normally happen to people? Or should I be worried?
