OT (sorta) sinus infection

I think this is the first time I have been sick since WLS. Seems to me I have a sinus infection -- they're all swollen and sore and my face is red and hot, plus I've been sneezing again. Normally I would take some of the antibiotics I have from a previous one but seeing as they are capsules I can't do that. Looks like I get to go to the doc and get some liquid antibiotics and such. Anyone been sick since surgery? How does the liquid stuff sit and or taste?
