I had the band about a month ago, and I feel great, and I had dream last night (no joke) that my band slipped. Now, I know that that's not true. But, how would one know if it did?

you have terrible reflux. also pb'ing and sliming. when the food backs up into the esophagus you will have pain. I promise if you suddenly have the symptoms you need to call the doctor and ask for a endoscopy.

That is good info to have^. I must admit I am a little paranoid about mine slipping as well.
