I used Neupro patches for some months. I suffered from:
Weight gain. I think I put on a stone in six months. I was always hungry.
Extreme insomnia, I did most of my sleeping during the day.
I dozed off while driving and had to give up my license.
I too became obsessed and hyper. There was a point at which I thought I was nearing a major scientific discovery and that I should disconnect my PC from the Internet in case the Chinese got wind of it.
Then there were those red patches on my skin.
My mobility improved greatly, but at too great a price. The one thing I noticed when taking Dopamine Agonists was that while I was taking them, everything seemed normal. But after I stopped taking them, I realised I had been a complete twit.
I hope it works for you, but please be careful.
