I'm kinda nervous!!!

Tommorow I start my 1st day of adderall, and I am very nervous. I have been on Strattera for 4 years and thought that it was not working as it had in the past. I was diagnosed with sever ADHD at age 25 and was put on 80mg of Strattera. Well I recently saw a psychiatrist and explained my situation, and he immediately said he wanted me to try Adderall (10mg to start). I have read hundreds of articles on this drug and alot of them really scare me. I thought Strattera was not doing me any good until these past 10 days of slowly being weined off. I feel so ADHD again, the way I had my whole life before being on Strattera..I am worried that I may have made a mistake by tring something new. The first 3 weeks of being on the Strattera was hell and I don't want to go through that again!!! I feel like I am stuck, because I have already been completely weined off and am to start the new meds tomorrow. To make matters worse I am 4 months away from my wedding day and am dealing with this mess. Can anyone share some words of wisdom? Or maybe a similar story?
