I have tried many different antipsychotics in the past and used to be very active but when I started on rispiridone I became very withdrawn they changed me to paliperidone but I was still unmotivated and withdrawn nothing seems to help. I've gained 3 stone with antipsychotics and the doc has now moved me to ability I'm on day 1 of taking it but am not positive wether it's going to work or not or assist weightloss
