Has anyone had caffeine???

Yes!!!

It's best to ask your surgeon and or nutritionist about caffeine amount and when.

But you can also check out a recent thread on how we all make our coffee. It's pretty popular and a wealth of knowledge.

I avoid caffeine.I had bad withdrawal side before hand...pre op when I stopped.Headaches etc...I had major withdrawal.Not going back to coffee right now .Will stick to teas.".

Absolutely. My surgeon advises to drink non-caffeinated coffee but....I couldn't do it. I began drinking coffee to my tolerance. The problem with caffeine is its dehydrating effects and messing with hunger signals. Recent studies show that caffeine may increase hunger due to stimulating insulin secretion, reducing blood sugar levels, and triggering increased hunger.

Moral of the story: take it slow. However, make sure you compensate for Water loses by upping your daily water/fluid intake. My recommended Fluid intake is 48 oz, but I'm getting around 72 oz/day.
