It is also prescribed for extreme fatigue, but if it is not prescribed for the 3 things that the FDA has given
approval for, insurance will not approve it. I took
Provigil for about a year, I was on suboxone at the time, which can cause excessive sleepyness, but it was more than that. In the end, I was tested for sleep apnea and ended up being diagnosed with RLS, which can cause the same symptoms. The provigil worked great, but like Eagle said, it is very expensive.
