Hi Peanuthead - welcome to SR
Go and see your doctor - when I stopped taking cocaine they performed several tests to check my liver, cholesterol, blood sugar etc. Its worth getting checked out so you can discover if you have any health isssues.
I was lucky and my health issues were manageable by making a few changes to my diet and avoiding drugs/alcohol.
This put my mind at reat as my drug induced paranoia made me belive that I had cancer.
