This was kinda of disconcerting I have not felt this offbalance in a while i have been having a lot of headaches the past couple of days (maybe driving?) and today although I had a very good day considering it was a drive her to school day i got a headache and took some tylenol then a little while later my legs were shaky almost like they might buckle and i feel pretty offbalance. Should I be concerned?? i have not felt so inmbalanced since the begining of this thing. Also I have never heard any of you complain about this but I have noticed for some time now when i feel crappy and dizzy or offbalance i have pretty bad dry mouth and it happens consistently enough i know the two are linked for me at least anyone else have dry mouth?? I am more concerned with the offbalance knee buckeling feeling....
