Hi all, thank you for your input, its all been very helpful. I don't have a problem with depression, I can't say I've ever had a problem with mood swings. I have had 2 manic episodes, both of them were triggered by anxiety lasting several days preventing me from sleeping. I believe that if I can prevent the anxiety and avoid sleep deprivation, I can avoid psychosis. The last time I stopped taking my meds I was stable for 4 months and I was working right up until my first day of anxiety. I didn't feel anxious during the 4 months either, I felt pretty much normal. The anxiety came suddenly, along with it the sleep deprivation, and at the time I had no Zyprexa to take as I had been on Sodium Valproate. I tried taking the Sodium Valproate as soon as I realised I was in trouble but it didn't work. When I went into hospital they gave me 10mg Zyprexa and relief was instant, no more anxiety and I slept for 12 hours straight. I am confident that I could stop taking my meds now and only take the Zyprexa as and when required when anxiety comes along, and it doesn't take much Zyprexa to have the desired effect, just 2.5mg is more than enough for me. I'm sure Big Pharma won't like this as they'll be making much less money, but at the end of the day its my health that is at stake, I can't go on putting on weight and having no motivation to exercise.
