Aw that sucks. Guess you'll have to do what I did when I encountered something similar and took it sparingly. Usually had the weekends off but it all depends on what you prefer. I'd advise you to be very strict with your lifestyle in order to function as best as you can without them, depending on how severe your adhd is.

Sleep early and make sure you get at least 7-8 hours if possible. Stay away from sugars in your diet. Write down some sort of routine so you can try to stay on it and keep up with daily demands.
