nausea 2 years post op

I guess I don't remember being sick since my LAP-BAND®®.....

For the past 3 days, I have been somewhat nauseated. Only threw-up once, the first day: only salivia since I was empty. At first seemed to be related to heat--first hot day of the year here; since, it comes and goes, and often happens while I am driving.

I am 8 days post-op for eye surgery. Prescribed Lor-Tab---the pill variety, and seemed to have no problem; nausea first occurred after several hours without pain meds. Also prescribed halcyon for sleep post surgery; again, nausea was 12+ hours after the last does taken. since the nausea started, I have cut back on the pain meds. Took halcyon last night, but I'm going to get off that--weird dreams.

No other symptoms like with the flu; no chance of being pregnant; no word from my LAP-BAND®® doc---I left a message though.

Anyway: I guess my basic question is this: If I am experiencing nausea, what can I do to relieve it? Mint tea? particular meds? Particular food? (the idea of crackers is not appealing; ginger ale would probably not be good either). such an easy question, but for some reason, I am feeling stumped.....and wondering if LAP-BAND®® has any special requirements for garden variety nausea (assuming there is such a thing from a "bug" or assuming that it is not related to slippage since i have no other symptoms).

thanks in advance!!
