tegan: i was looking into liquid vitimins but i have found there too pricy
How much it is worth to you to remain a vegetarian is a personal thing.
What benefit you get from being a vegetarian is a subjective thing.
Assuming you have a moderate diet you may get away with only having a multivitamin once or twice a week.
Or just crush up the regular pills they may not taste to good.
If you are having a lot of reflux as well may you have too much fill?
I have had my band 10 months and have never had reflux that lasted more than 20 minutes.
