Last September, I started using low dose Adderall (5 mg BID) for migraine associated hypersomnolence. I have found it helpful, but not yet optimized.
It allows me to mostly function at a basic level which is better than feeling sleepy all the time.
I have seen others express an opinion that Migraine may cause mental fatigue and drowsiness, and I believe that this is true. I have a recent anecdote to share in support of this idea.
I have been using a 5 mg dose of Adderall to help me wake up to a state of mostly full alertness. I have observed that it requires about an hour to take effect and wears off about 6 hours after dosing. The way that I have been using the initial dose is to take it when I initially awaken, then go back to bed and sleep until the Adderall wakes me up about an hour later. Then I am good for about 5+ hours after which I take a second dose which carries me mostly through the rest of the day.
I had a migraine episode recently that came on about an hour after reawakening. It was part of a several day long episode. This time, I noticed that, while the Adderall initially awakened me as usual, the migraine caused noticeable drowsiness, and I immediately took a dose of Imitrex, which is my preferred treatment. The migraine abated after about 2 hours, which is typical for me. I noticed that the drowsiness lifted and my mental state returned to where it was before the migraine onset. Interesting. My conclusion is that migraine *itself* causes a suppression of CNS activity directly resulting in drowsiness which can overwhelm the effects of low dose stimulants. (Possible RAS effects?)
So far, the Adderall seems to be the most effective treatment for me for migraine associated hypersomnolence. I cannot tolerate caffeine in more than small trace amounts, I get hideously intolerable multiple side effects from it at doses of much more than 10 mg/day. I have tried Provigil; It is no good. It is a "dirty" drug with poor effectiveness and several undesirable side effects including stimulation of painful bruxing. Adderall, at my low dose level has almost no noticeable side effects, but has some short term variability in its pharmachokinetics that need to be worked out with possible dosing adjustments and maybe a time-release formulation.
I decided to try the Adderall because I came to the conclusion after many years of observation that I was not having a *sleep* problem, but a *Wake* problem. It was not that I was not sleeping adequately, but that I was not able to awaken fully and maintain a normal waking state throughout the day.
I am retired. I do not have any externally imposed schedules, so I can experiment.
