tourette's syndrome
"The first time I was prescribed Olanzapine I was on it for about 5-6 months. The tics were reduced by about half which was great for me. However I soon realized that there were subtle side effects which had horrible results. The medicine made me very hungry which meant I ate a lot more and as a result I gained around 20 pounds in a very short period of time. Another side effect was drowsiness and lethargy. I slept a lot and took naps during the day. I trialed the medicine again recently and the same side effects occurred so I have had to stop this medicine and try something else."
