Vomiting after taking meds...kinda gross, sorry.

So, my dr after I was running a fever of 103.3, put me on antibiotics and prilosec for the rotten acid reflux.  Last night I got my horse pills of antibiotics and of course had to crush them. I about threw up after taking them. This morning taking the antibiotics and prilosec again I gagged, mouth watered, but I didnt get sick. Now, I just took my prilosec with cottage cheese. My mouth started watering, ran to the bathroom and threw up, literally.
WHAT Is going on with me? Anyone else have open RNY and have this many problems? Im scared to take my darn antibiotics in a bit cuz Im sure Ill get sick after taking them too. Im very shocked he didnt give me a liquid, maybe antibiotics dont come in liquid? I dont know. I have no appetite. I know Im literally starving myself. I had yogurt this morning at 6am.  Just tried cottage cheese at 1:30pm and puked it up with the meds Im sure.
This is frustrating. I still have my reflux too despite taking prilosec. I dont know what to do anymore. and I do NOT want to lose my hair but I cant get my protein in either. The thought of my protein shakes makes me wanna puke. HELP!

I know this is hard for you. I know this is late, I missed your post!

A couple things to remember and maybe this aids in the issue.
When taking an antibiotic avoid caffeine and dairy products as much as you can. I know that we need these for our levels. However, the dairy products kind of make the antibiotic useless so to say. It weakens the effect.

I only know this because I am taking one right now for a UTI.grrrrrr
I also have been removed from my vitamins for 5 days while on the antibiotic because the vitamins etc.. attach to the antibiotic and once again make them kind of useless to do their job.

Your really struggling with a lot of issues and your in my thoughts! I hope things get easier soon for you. It just sucks
