Nothing too bad. I gained weight at first but metformin has helped me lose it and mostly keep it off. Like most people on it I drool at night in my sleep but nothing awful. I do get dry skin on my chin from that so I need moisturizer. I wear incontinence pads at night because sometimes I sleep too soundly to know I need to get up for the bathroom. Sounds bad but I adjusted quickly and I no longer think about it much. It's just a dribble, not a soaking. I do get hungry and thirsty after I take it until I fall asleep so it's good to have lots of fruits and vegetables around for snacks. I need a lot of sleep but I'm on more sedatives than just the clozapine so I think that's more the issue.

Honestly it sounds a lot worse than it is. Everything is easily manageable and I'm completely used to it all. And I feel so much better that I would put up with a lot more than this. I've not been on a med that didn't have side effects of some kind and some of those were a lot worse to experience.
