my doctor has giving me meloset 3mg and quitipin 200mg, from the time i have started taking these i have lost interest in doing anything, cant concentrate on my work, become very lazy in doing anything, even socializing, i have put on a lot of weight and inspite of taking suppliments unable to shed a single kilo gram.i used to take nitrosum 10 mg and toporimite 100mg which never made me add on to any weight. Do you think by going back to the previous medication would help my purpose?
