> I assume that Amitriptyline is associated with weight gain and lethargy as well as significant sexual side effects, correct?
Weight gain - yes.
Lethargy - not necessarily. Sedation is not lethargy. One can become quite tolerant to antihistaminergic sedation.
Sexual side-effects - less likely with amitriptyline than with clomipramine or imipramine, since amitriptyline's SRI isn't that strong.
Also, amitriptyline's affinity for 5HT2A-receptors (as an antagonist) is pretty close to its affinity for serotonin receptors, and 5HT2A-antagonism is likely to counter SRI-induced sexual side-effects.
