We have the same consultant, so I'm on the same regime as you. Had my op 2 weeks ago. I also got that weird hiccup - I interpreted it as some kin of muscle contraction. but I think its trapped air. I haven't had now for about 3 days, but I dont know if it is gone for good or not. First 3 days out of hospital were pretty grim, I found getting in more than a litre of liquid really hard. But hot drinks were so much easier to get down, and now manage 2-2.5 litres a day. Also food got better after about 6-7 days, and now I'm eating pureed meat and fish (even beef) no problem. Your pouch will be still quite swollen, so it will only get better as you heal.
