About a month ago I started on the fentanyl patch, first the dosage was 25, then 50 and now I am on 100. What has been happening lately is I am constantly falling asleep. This from a person who could never get any sleep. My energy is so low. I still have difficulty understanding how fibromyalgia makes any sense. Maybe I'm in denial but I just don't get it. Its like it came out of no where. Now I have zero energy for the most part, everything bores me, and I just don't feel good but I don't feel sick. I dont know if this makes sense to anyone. I am also taking care of a stroke victim, who thankfully, is getting better daily, but this person use to be my care giver. I am just tired of being tired and tired of doctors and wonder what is the point any more. One thing for sure is they cannot fix this. Could any of this be a side effect of the fentanyl?
