Yeah I was told no drinking 30 mins before no drinking during and no drinking till 30 mins after eating. I do pretty good at this unless I feel something is stuck... but if something is stuck and I drink it a lot of the time results in me purging which deals with the stuck item... If I find what i have eaten my sleeve doesn't "feel" right i will have a small drink (sip) and within a few minutes the feeling passes. But as a normal rule i don't drink till quite a while after.
