I took Invega for a long time and it worked but I did have to increase the dose to start feeling better. I don't remember the dose but it was up there was weight neutral also. I could not tolerate Risperdal at all. Honestly the only reason I stopped Invega is that I actually started to drool and zone out while doing stuff. I was happy that from the start it it was the only medication that didn't cause Dry mouth.

I hope Invega kicks in and really helps you
