Thanks for the input guys, I've been feeling a lot better these last couple of days. I'm sure part of my sleep issue is the tinnitus which seems to have flared up, a couple of weeks ago it had almost gone and didn't bother me at all at night. I have a doctors appointment Wednesday so will see what he says although I'm not expecting much.

@Bud Glad to hear you're doing well, do you think you've about recovered? I've progressed steadily, even the last few months have seen improvements so people who put time limits on recovery I think are wrong.
