Thanks for all of your replies.

Yes it was amitriptyline and my doctor said that it would be enough time and then when I emailed her last week she said I will have to see another specialist in China because it hasn't got better.

So yes it was cold turkey. I was fine for the first few days as I was on holiday and relaxing but it really hit when I got back.

Thanks for the link. I'll take a look. I guess I need to make an appointment with the doctor to get some more!

Today wasn't so bad. I went outside for a walk and some fresh air but now feel exhausted. I feel like i'm back to square one.

Oh and the concussions? The first one I was hit by a motorbike at high speed, the second was a freak incident where someone fell on me and we both fell into a wall and I knocked my head on the wall and the third was I felt dizzy and just toppled over.
