Hello there! I was also banded on the 12th so I know exactly what you mean. My advice to you would be to make sure you are drinking enough Water because if you are not then you could be de-hydrated, which could be making you dizzy and lightheaded. Also, if you can, try and walk around as much as you can and definitely practice your breathing because I just found out last night after 7 hours in the ER that I picked up pneumonia. If you continue to feel lightheaded and dizzy, I'd suggest taking dramamamine, an over the counter drug for dizziness, lightheadness, and nausea. They come in orange flavored chewables and work well!
Good luck to you and hang in there! :biggrin:
