Hi never.happy, I have been on Provigil for over a year now. I can honestly say it worked wonders for me. I had to get a pre-authotization and fought for over a month with my insurance company, but I was able to get it. Provigil has helped with my depression and overwhelming fatigue that kept me in bed most of the day. Now, you need to know that it may intensify extreme anxiety in some people and also be careful if you have any type of manic episodes as Provigil may exacerbate the highs. I haven't really had these side effects. One bitter sweet thing about Provigil, it may help you lose weight by giving you energy and greatly elevating your mood. This was a great side effect for me, until I became Anorexic, but that is in NO WAY the drug's fault. I take one 200mg tablet in the morning and 2 more about noon. You really need to limit your caffeine intake on this medication. Still, I encourage you to talk to your doctor about this. I am not an expert, I'm just someone who takes the aforementioned medication and wanted to share my thoughts, feelings and personal experiences. Wishing you all the best! Again though, it's vital that you share all your symptoms with your doctor. Good luck and wishing you the best! Take care
