You can take a very small dose of klonopin along with the adderall, making you feel less anxious without taking away from the stimulation. Save the majority of the dose for the comedown. So if you have one klonopin pill, take 1/4 at the beginning, then 3/4 at the end. I was always prone to anxiety and panic attacks, so would take .25mg of xanax when I dosed the adderall, and then 1mg at the end for sleep.
