Hi, on the whole yes they're fine, I had them often immediately post op. I used the unflavoured one you can get from holland & Barrett, with no major problems. I did however in the first couple of weeks seem to react to the milk as I'd feel light headed & have chronic stomach ache & the trots after eating or drinking milk based products. Not so much yoghurts but glasses of milk or shakes, so for a brief time only again a week or so I changed to soya, rice or oat milk but mainly soya milk, it gave my pouch a chance to settle & I was soon back on the semi skimmed cows milk again.
Another idea to boost the protein while having a shake type drink is a quarter cup each of milk, fage or other 0% Greek yoghurt, fruit (tinned in juice (drained), fresh or frozen) mixed with a scoop of plain protein powder all blitzed with a hand blender or similar makes a lovely flavoured shake/smoothie without added sugars etc. that you can change without having lots of expensive flavoured protein powders.
Hope that helps. I'm now 15mths post op 8st down overall pre & post op in size 10 clothes from size 20-22's & a stone ish away from a healthy bmi & weight excess skin allowing, but even if I can't hit that the hospital are pleased with me as overall I've lost 93% of my excess weight so far so I can see where they're coming from but would love to hit the healthy bmi & weight for my height even if its only just in at the top end.
