Thank you for your input. Yes, it is much worse when I am tired. In fact, three weeks after my surgery, I ended up taking care of my husband and my mother, both in hospital beds at opposite ends of the house. My mother had a compression fracture in her back and my husband has been down since December with a brown recluse spider bite. Mom went back to her apartment Monday and my husband returned to work tonight. I did have help off and on and the church brought meals for two weeks, but I was zapped and am finally starting to relax. They have had me on antibiotics since surgery for an uncontrolled sinus infection. I had sinus surgery last week and hoped that this foggy feeling was related to the sinus more than the tumor. I was surprised to hear that after my friend's spinal tap, this feeling in him disappeared. Could it have something to do with cranial pressure? Makes you wonder. Do either of you drive at night or work? I can't imagine myself working with this. It totally messes up my concentration and memory. Hopefully, with rest, it will subside a bit.
