Hi Sid,
Your GP can prescribe this, but this medication is indicated
for work shift disorder, and excessive daytime sleepyness associated with Obstructive sleep apnea. 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.
