I have been on Olanzapine for just over 2 months now, that is when my anxiety started. It has really helped. I was on 1 x 2.5mg for a while, then had a really bad week and upped it to 2 x 2.5mg. Stayed at that for the past month, but have now gone back down to 1 x 2.5mg, going ok at the mo. I found that taking 2 lots was making me extra drowsy, weight gain and it was difficult to concentrate at work, so hopefully I can stay on just the one tablet. I am having couselling, doing yoga and taking vitamins, so I hope, in time, I can come off medication completely.
