Welcome to HW MeChelle
you will find a lot of support here,
well for your husband, do watch him because stoping a depression med cold turky can have problems (he might go into a very bad depression state for a few days or more) though people do react differently to meds so hopefuly this will not happen to him but I have seen it happen to others when they did stop the med cold.
As I was saying he might go into a deep depression and can/will have mood swings (keep an eye on him to make sure it doses not get to bad) he should call the doc and talk with him/her to see if there is another med that he can take that will have fewer side effects.
wishing you and your husband the best
let us know how thing go
