I'm just shy of five months out, but I am ALWAYS tired. Always. My husband let me sleep in last weekend, and I stayed in bed until 11, and I could have taken a nap. It's horribly frustrating.
I had a sleep study done, and while I don't have apnea, I never went into REM sleep because I woke up so many times. They gave me Mirapex for RLS, and that helped some, but I don't always take it because of the side effects. I have a prescription for Ambien and I've been debating starting that up.
If I took both of them, perhaps I'd get good quality sleep. That's what I'm missing. I get tired of popping all the pills all day long, so I've generally avoided these and I was hoping as the weight dropped, I'd get some energy. However, after reading this thread, I'm thinking perhaps I should try taking the pills regularly and see what I think then
Good luck! Hopefully the sleep study is enlightening!
