Thank you everyone so much for your replies! Last night was rough on me, I panicked!
@Sosewsue61 I'm glad that's normal. I got worried that I might've done something wrong! I will try those foods and see if I can have them. I have googled lots of recipes and stand-alone foods but some I can not afford, so I gotta keep it "cheap". I will go to the store today and try to get all the things you named in your post! I usually manage a max. of 33oz, I'm trying real hard though but I've never been a big drinker, this is my biggest challenge I think. I was thinking of putting tiny water bottles in every single room in the house and take a single sip each time I pass those rooms, does that sound like too much?
@GlowingGal It's comforting to know I'm not alone with the struggle and to know that you got an alternative already. I would love to try chicken, fish and salads. To be honest I've had a teaspoon of feta and tuna before and both went down well, the tuna felt a bit heavy though. But since the surgery I have never vomited or felt sick so I feel open enough for those foods already, it's just I'm really afraid that if I don' stick a 100% to the plan I will not lose any weight. Perhaps I'm just stressing myself out too much, I'm just really petrified of failing.
@Tina Meinkowsky I've bought Whey Protein Powder online the other day, 2kg (4lbs) pack! It is recommended to take 3 spoons of it (which have 30g of protein in total) with water or milk and I've tried that, but he consistency is so thick and heavy that my stomach can't bear it, after a single sip I feel "sick" and stuffed, it's very uncomfortable. I'd mix the poweder with smoothies but it makes the smoothies thick in consistency so I struggle again. The best way for me would be protein water but for some reason that doesn't exist in Germany? Aren't there any tablet supplements with proteins?
Thank you all again tons for your replies!!!
