I have had MRSA about 3 times in the past year. I have problems with fatigue and can sleep for long periods. I have had my thyroid checked and treated, testosterone checked and treated, am on meds for depression, Ritalin to help me get up in the mornings, but still feel exhausted most of the time. I ve noticed that when I take an antibiotic, that all goes away and I start to feel like myself again and have energy, but then after about a month, I end up going through another cycle that can last for 3-4 months. Is it possible that it is all MRSA related?
