... mail order prescriptions). I was out for 3 days and I didn't sleep except for about 3 hrs. in those three days. I ended up having a seizure and in the ER. It scared me badly. That was a week ago and I am still very sore from the seizure, tired and lethargic. I finally got my prescription but I absolutely have no energy. I have Fibromyalgia and I take Cymbalta and Oxycodone (Just started that last week. Was on Norco for about 4 years before that.). Do you think the way that I am feeling is due to the seizure or because of the Oxycodone? I am so tired of all these pills, but my depression is deep when I am without it. Thanks for any replies
