Aderal is amphetamine salts. It works great for somnolence and sleepiness. It counteracts the effects of the narcotics so that you have a lot of energy even though you're taking a lot of narcotics.
The problem with it, of course, is that it takes more and more of it to be effective. So I wouldn't take it unless I knew I had the discipline to "rest" from it on a regular basis. Take if for a few days, and then take a few days off from it. That way the same dose is effective over time.
God bless,
