So my surgery is scheduled for October 1st, and my surgeon put me on a 2-week liquid diet starting this past Friday. I'm suppose to drink 3-5 Bariatric Advantage shakes a day and drink 72-96 ounces of Water. I made it through Friday fine but by Friday night I was having uncontrollable diarrhea to the point where I barely slept and had 2 accidents in the middle of the night. Saturday and Sunday I was travelling and in long meeting both days, so I did not follow the liquid diet... but did eat healthy (lean Protein, salads, veggies, etc.) I'm back on the liquid diet today and have only managed to drink one of my shakes because they completely disgust me. The smell of the powder by itself makes me want to throw up. I'm at the point where I'd rather not eat anything than drink another shake. Two questions:

1. Anyone know of anything I can do to get rid of the diarrhea, or will it simply go away after a few days? I'm choke down the shakes if I have to, but the thought of spending two weeks in the bathroom makes it harder to drink.

2. Is 96 ounces of water a hard upper limit? Is there any reason to limit the amount of water I drink right now?

I've now found that if I mix the Bariatric advantage with skim milk tastes much better, but still have an issue with the foam created from shaking it. Any ideas?

I'm on Optifast 800 shakes also. Not bad but the liquid diet is what's rough for me. Surgery is October 15th

Thank you all for your suggestions.

I would use skim or almond milk. I tried using my blendtec blender, but it was awful... way too foamy. So I used the shaker for the remainder of my pre-op diet. Every now and then it'd come out pretty smooth... but other times too foamy. I never got the hang of it. One thing that seemed to help was to get it as cold as possible, seemed to go down easier. So maybe try shaking it up and then putting it back in the fridge or freezer for a few minutes.

I haven't used the BA powder since surgery. I've been drinking the premier Protein ready to drink shakes which have a much better taste with no aftertaste. One note though, the BA protein uses 100% whey isolate while the Premier Protein uses a protein blend with whey concentrate as the third ingredient. You can research the differences between protein's, but generally, whey isolate is considered a higher quality protein and may be better absorbed. In the end, I decided I'd be miserable using the BA, so better to drink the Premier Protein than nothing at all.
