I got loss of libido and anorgasmia at the start, but these are a lot better now. The first six months or so were the worst.
Apart from that just weight gain really. I've gone from 90kg to 100 in about a year and a half. I do tend to eat a lot of carbs and sugary foods, though. I seem to have stabilized at 100kg, thankfully.
Bear in mind that I'm on the max dose of Nardil, 90mg. You may well do OK on a lower dose, so side effects would be less of an issue anyway.
