I suffer from depression and was prescribed matazapine last year all year i was on weight watchers which i had been on before and in doing so lost 6 stone and last year i rejoined weight watchers again and followed the plan religiously and to my disbelief put on 3 stone and this happened within the first three months so of course i became more depressed i also noticed that my hands and feet would swell so i had a hard think about what i could be doing wrong and realized that the weight gain only occurred whilst on the tablet so i revisited the doctor and they then prescribed trazadone and low and behold as soon as i changed the meds the weight fell off and the swelling stopped doctors should really inform the patients that weight gain could occur as this made me feel 100 times worse.
