I was on Adderall, then tried Dexamfetamine. I was on 30mg a day long lasting I think. For the first six months the medication worked, then I began to feel sick and paranoid. My social life fell apart and my work became mediocre. Now when I take any stimulant after a couple hours I start to feel dehydrated and light headed. If I continue using for a couple days I am unable focus on anything except a couple intrusive thoughts. Different medications work for different people, so please don't ignore ADHD treatment! It's a powerful tool, just be careful not to cut yourself like I did.
