Hi Stevie. I just read your post and i releated to your problems so much. I received a concussion after i was assaulted in May 2007, and have had the same problems as you since. It's the headaches that are the worst for me, and sleep is a big problem too. I'm still plodding on, waiting to find the magical combination of pills to work for me.
I was doing shotokan karate before this happened to me and haven't been able to train since. I can understand you, it sucks when you cant do something you love to do. I haven't been able to work the last few months either as symptoms seem to be getting worse instead of better.
The alcohol has affected my social life too, its horrible being young and not being able to go out and enjoy nights with friends the same as before without suffering for days after!!
I've read so many posts on here about people having the diagnosis problems, your right it does seem too many people/doctors are ignorant to PCS and it does begin to feel like your going mad after a while. Your not alone!
I'm so glad you found Neurotalk, its helped me alot to find other people out their who DO understand you.
I look forward to talking with you more.

All the best
Rhona
