Congratulations on the new job! In this economy, you are fortunate!
Don't panic! Both the meds and your doc are doing exactly what they are supposed to do. You are on the lowest possible dose and it works for only 3 to 4 hours. Now that your doc knows that it is working, he will simply have you take another pill after 3 hours or put you on an extended version.
Just let him know what is going on.
By the way, for any medication I take - I always google it to find out side effects, duration etc. If you had done that you probably would not have worried quite so much.
Any other questions about adult ADD? I would also love to know (after so many years) - what steps you took to finally get diagnosed. Best wishes.
Oh yeah he put me on ritlian becuase it was inexpensive for me since I don't have any insurance.
