Tom:
There was a time when I felt my wonky-headedness was subsiding back in July of 2009 (1 year post-op). My head felt clear like it hadn't felt in a couple of years. Then I took a vacation involving plane travel. To this day, I have not recovered from the jetlag. In my pre-AN past, I've taken many vacations involving plane travel across time zones. It's not unusual for me to take up to a year to recover from the jet lag and for my body to get back to my normal sleep schedule. But now I have to deal with the wonky-headedness, too.
My balance, however, was not affected with the return of my wonky head. There are times of the day that my balance is better or worse than others, depending on how tired I am. But in general, I feel that my balance has improved.
Give it time. Five months is not a long time. At 5 months post-op I remember trying to take on more physical activity because I thought I felt well enough or strong enough to do it. Payback was a *****. I did feel I had taken a step backwards afterwards. My Dr. had warned me about this. She said that my progress graph would take a dip on these ocassions, but over the long term, the trend of the graph would be upward and forward.
