I'm 9 mths out since sleeve and in the beginning completely gave up all coffee and soda. A few months ago I started drinking crystal light with "energy".... that has been giving me that boost I miss. After reading the label it actually has more caffeine in it than in soda, so started wondering if it might cause any issue. It doesn't have any carbonation like soda but wondering if the caffeine is an issue? Anyone know?

My surgeon said it is important to refrain from caffeine during the healing stage, but it's ok to have again about 2 months after surgery.

I think it can cause ulcers

No no..the reason doc's tell us no caffeine is that it can cause you to eat more from our minds being programmed from us usually having it during meals. I was told I could have coffee in moderate after one month. I started back on limited soda after 2 months. You'll be fine....everything in moderation (since you're forced to) will be ok *sips his Diet Dr Pepper while typing this*

Hello, I went to all my classes and they said no beer or soda (anything carbonated) because the carbonation expand the soda. that's what I understood.

LOL, i mean the carbonation expands the stomach.

I was told it causes dehydration.
