im only 13 days p.o and i can already take decent sized gulps without a problem so i would say you should be fine.. some people just take longer to adjust then others i assume. i know i shouldn't eat and drink at the same time.. but i randomly have lapses in my memory and forget im not supposed to do it and do it anyways.. lol and after a few sips i go ...oh crap.. lol let me put that drink down... funny part is there isn't any discomfort when i do it so i have to really pay attention.
Anyways, im sure it will get better for you over time.
