I've run into the same problem at work trying to concentrate. I'm a nurse. I'm ok when I am actively taking care of patients but when its time to sit down and do all the paperwork I have a hard time sitting still. Like Bipolar nurse I find myself walking up and down the halls. Somehow I manage to get everything done. I was having problems with my memory and I'm blaming my meds for that so I stopped taking them last week. I'm a little hypomanic right now and I find myself talking too much and very restless. I think Im driving everyone else crazy.
