Misty,
You are correct clomipramine is a pretty potent seratonin reuptake inhibitor. And the active metabolite is a potent norepinephrine/noradrenaline reuptake inhibitor. Like all tricyclic antidepressants they are frequently associated with weight gain so frequent weight checks during treatment are important.
Dry mouth and constipation are not uncommon, and can go along with the increased appetite. Sedation, fatigue and drowsiness are notable side effects however after taking it for a while that can improve.
Hope it works well for you folks. There is nothing worse than watching our babies suffer. While I was working with Cali's anxiety I was using exposure and increased exercise. While this was going on it increased her confidence which was a major boost for us. As her confidence grew she got better a dealing with the anxious moments -- of course that night have backfired since she now thinks she can handle anything

. The bigger the better!
