Hi @jeriliz and @johnbishop. I do take Modafinil. It is my "speed". I say that because so far that is the only thing that gives me any sort of help for my fatigue. I take 2 200mg tablets every morning. I believe that is the max dose, or at least for insurance. It is very expensive. I am on Medicare and since I am in Arizona, I can't get a supplemental insurance since I am on social security disability. The stupidest thing I ever heard but it is what it is. You can find coupons for it sometimes on the internet.
Anyway, I was put on that because I have Chronic Fatigue Syndrome. Then I had a surgery in 2014 where my celiac and sma arteries were compressed from my diaphragm. I have later come to learn that it is called MALS and a very rare disease. This also adds to the fatigue and I have a number of other medical issues. I still nap everyday. Some days are better than others, and I can tell if I over do it. I could be down for a week. I can tell though a difference if I don't take it. For example, after another surgery, I didn't take the Modafinil since I was resting from getting stents in the arteries. When it was time to start moving around I took one pill and could feel a little more energy but then that wore off, then went back to the 2 pills. I am still looking for other things to help with my fatigue. I read savilla, I think that is how it is spelled, is good for fibromyalgia and fatigue. I will probably be adding that after my surgeon visit next week. I hope this helps you. I know every one is different. I have a bad stomach and I can tolerate this pill with no issues also.
Let me know if you have any other questions. Good luck to you.
