Hope your both doing well, I didn't really have pain just uncomfortable for 2 weeks or so, it does pass honestly. Smelly burps I'm afraid can continue to the end, your not drinking enough. I know if I've been busy and not drinking well I burp and that soon reminds me to drink more water.
Hope Xmas hasn't been to bad for you, I've been naughty, eaten some sweets, crisps and drank voddie and coke, but now in moderation. I'm not too worried as I have a fill on the 16th of jan and got to be on fluids only for 5 days beforehand so anything I'll gain, I'll soon lose on the liquid diet.
