I've heard of Latuda, but I don't think it's been licenced in the UK where I live. I know that almost all anti-psychotics make you gain weight, but it might be worth it if the drug helps you. I encourage you to read up on any new medication, as well as asking the medical staff. If you really are going to come off drugs that your doctor has prescribed, do it slowly. Don't do it cold turkey; I tried that a couple of times and it was a nightmare. By the way, there's no need whatsoever to be embarrassed when going to the pharmacy. The pharmacists see many psychiatric patients. My own are fully aware of my psychological state and my drug regime and they go out of their way to be helpful. You have a serious illness; for your own sake please don't add unnecessary embarrassment into the mix.
