I was on adderall for 23 years. Very addicted to it, psychologically. I have been off of it for 3 months. I gained alot of weight. My blood pressure is high and mostly because of my weight. I am only 29 yrs old, and instead of being put on blood pressure medication, my doctor has put me on phentermine to lose weight. I've been taking it for 15 days now. It doesn't seem to affect me psychologically, except that i am not hungry. I really don't want to develop another addiction. Any advice?
