For two years I suspected that I was addicted to non-prescribed amphetamines and looked up the symptoms for addiction; I realized my suspicions were true. I took about 60-100ml per day, average of 2 times per day, 3-5 days per week. I stopped cold after it got to the point that I was experiencing extreme physical and psychological comfort every day. I haven't taken the drug for over two years now and am having cravings for it again. It's odd to me because since the day that I stopped, just the thought of taking the drug made my stomach turn. Possible causes why the cravings are kicking in so late?
