I am 3 weeks after surgery. Been fat always. Had the sleeve in 2016 and did well for a few years. The plan was to convert then to the bypass once my BMI was down but then the insurance company decided not to pay and it was a battle til now. I had it 3 weeks ago.
And this is so much worse than I could have ever imagined.
I realise now that they put me on anti nausea meds and took me off my antidepressants that I’d been on for about 8 years. Cold turkey. I am now a bitch who yells and snaps or cries. That’s it. I had a lot of pain post surgery and was in hospital 6 days not 3 - as with probably lots of us, I’m tolerant to pain meds so I am only now managing with plain paracetamol. But I feel nauseous all the time.
OK.. so it’s piteous.. but I really think that I’d be ok if I could stomach any Protein Powder at all. I just can’t. It’s all completely disgusting.
I’m in Europe not the US but I ordered over €200 of different products. All made me vomit. No taste ones, flavoured ones, ones in Soups etc. all the same!
I sit here with no energy and frankly no will to live. I have a bucketload of pills that I could take but I have kids so I just can’t do that. Somehow this has to turn around.
But how?
Has anyone been through this?
I wanted to move to the country and grow delicious wonderful food and have a few hens, not bankrupt us on buying disgusting “shakes” and being bloody miserable.
I don’t weigh. I don’t have scales. I just know that my body is eating itself and I’m not giving it enough Protein because I just vomit it back, even the mini-sips. And how miserable is it to be only about to drink 50ml in an hour and have to fill it with sips of stuff that makes you want to vomit… then you do vomit!!
Google anything about Protein Shakes that are any good and of course, they all come up.
Can someone actually tell me if they have been in this situation and if they have found any protein that works?
What a baby I am but I am at the end of my rope. I appreciate any ideas, especially from people in Europe. My “bariatric team” are useless. Just useless.
