Suggest Treatment For Insomnia And High Libido After Using Sertraline

since stopping my anti depressant medication 2 months ago, my libido has returned to its uncontrollable high. I suffer with insomnia anyway but this increase in sex drive is only allowing me on average 3hrs of sleep per night and is ripping my marriage apart as my husband has zero sex drive and never has. I don t wasnt to go back on the sertraline as it did make my insomnia worse and i gained weight. I can t cope anymore with no sleep and such a high sex drive. Can you help please?
