Elizabeth, I have been feeling light-headed, my hands are numb and cold intermittently. Also, I have been very tired even after going to bed very early. I feel ok then at work about 10:00am I can barely keep my eyes open. I don't drink as much water as I should. I did make an appt with my pcp. Also, my body is weird. I have a super infection (pseudomonas) in my sinuses which I have had for a few years, this could also be causing my symptoms. My doctor believes I am a carrier and have made numerous attempts to irradicate it to no avail. At first I thought it was not getting enough food because of the problems with my band but after most of the fluid was taken out I am still having the same problem even though I am able to eat more.
