Are you possibly drinking too fast? I never experienced this, but I am wondering if it would help to sip your liquids if you aren't doing so already. You probably still have some swelling in your sleeve. Hope you figure it out soon!
Also you may have problems with temperatures of liquids- at first very cold liquids make me puke. So I ended up drinking a lot of hot beverages and sucking on popsicles inbetween.
Eventually you get back to something like normality.
