Hi Zack. :)
It takes a surprisingly long time for some drugs to completely flush from your body. That's why we get so many questions about passing drug tests.
From our experience over the years, side effects go away in a couple of days up to a couple of weeks. Until then, be gentle on yourself. Try easy simple exercises, gentle stretches, and massage. Eventually everything will flush clean.
If it doesn't, you have to talk to your parents and doctor/school nurse.
