This is question you probably really need to be asking your doctor, and not relying on us. When you tour, your body's chemistry is going to completely change. Example: You will eat twice as many calories, you will burn twice as many calories, you will drink far more fluids, and all other kinds of physical changes including possible weight loss... ADD/ADHD is also a physical disease based on chemicals in the brain so while the medicines you take now may work, they may work differently while on a tour. But certainly, ask your doctor about this for a good answer.

Best wishes.
