Hi, I am experiencing extreme fatigue. I sleep over 8 hours per day and would continue to sleep if i didnt have a job. I have a hard time exercising because i have knee replacements, neuropathy in both feet and a couple bolts and screws in L3 and L4. I have been taking percocet, neurontin,mobic,wellbutrin for the past 10 years, i also take cymbalta. I understand that my medication alone can bring on fatigue, but i have never felt this sleepy allllllllll the time Ever. i take all of the b vitamins, d, fish oil, coq10, potassium/magnesium. HELP PLEASE!!!!
