you always feel that way.
Not always, but often. I brought it up with the psychiatrist on my last visit, and I might get a referral to a neurologist or some new meds to try next time I see her. My uncle has the same problem of being tired all the time and sleeping excessively, and I've started to suspect that I suffer from narcolepsy.
Wow, I suspected the same, but because you explained your problem in such detail, I assumed you had already considered and then ruled out narcolepsy!
Whatever it is, I hope you get a dx and useful treatment soon.
