I've been taking Duloxetine for two weeks now. One 30mg a night (due to go up to two a night for two weeks then three a night for two weeks!) and I don't know if it is the drug or just my fibromyalgia in general but I've been SO thoroughly exhausted lately. Today was extreme. I could not move. I've been in bed all day. It's now 7pm and I've just got the energy to make a cup of tea. This is the worst case of tiredness I've ever ever experienced . Is this to be expected and I just have to go with it or should I tell the dr!? I accept that I have to give them a chance but I'm also worried because as I've said, the dose is going up and up over the next month!
