Sleep is not fully restorative thus the chronic low mood and tiredness and amitriptyline is better at restoring sleep quality than desipramine.

Thanks very much for sharing your experience.
From the above, I take it that you like amitriptyline better than imipramine - at least in your experience? It looks like those are probably the two that I'll be choosing from...
Given the fatigue issues, you dont' find that amitriptyline's sedative side effects are a problem? Or are they similar to imipramine's, and therefore irrelevant in choosing between the two?
Btw, do you take the amitriptyline at night - to "take advantage" of the sedative effect? [as opposed to taking it in the morning & being sleepy during the day?] My pdoc mentioned that idea, which makes sense - but I'm just skeptical that PM dosing will take care of the sedative side effects...
In any case, I'd be interested in your opinion, should you have a chance to read & reply to this before I meet w/my pdoc tomorrow evening [10-26].
Thanks again for your previous feedback.
