Could someone please tell me when the constant burping will subside. It is quite painful, and even though I have been careful to take little sips and make sure I am not swallowing air, I still end up with huge burps. It is hard enough to get the required amount of liquid down without having the discomfort of gas, never mind that I can't return to work if every time I sip, it sounds like a pig farm.

Any help is appreciated.

I had that for a couple of weeks, and then struggled with some hiccups after that, but it did subside Hopefully the same will happen for you. Keep being careful.
