I'm on an AD for the mild depression I had. So the "I don't feel like doing anything" fatigue is gone. Of course now I'm a little frustrated that the body can't keep up with what I want to do. Can't take any of the meds, so learning how to rearrange things in my life to handle this.
Because my fatigue was so bad, they have tested almost everything under the sun. Thyroid, B12, D, etc. etc. Everything has come back at normal levels.
Think I might request a sleep study since my dad has sleep apnea. Couldn't hurt.

Hope you feel better soon.
