Mark, your statement

"Once concussed, always concussed. That means your system will always be sensitive."

scares me a lot, to be honest.

Is it possible that a minor concussion, with no headaches but just dizziness in the days after, going to haunt me forever? And why is that?

I take what you said seriously, view your expertise and the fact that i managed to bring back my symptoms a month later after vigorous running...

It would be really depressing to have to stay away from alcohol for more than 6 months...

I do not mean to change the discussion but i guess everyone would appreciate a clarification of your above sentence...

Thanks a lot as usual.
