did erythromycin work for u?

i started erythromycin a few days ago and so far i have felt so much sicker than before, which is a lot bc i was already hella sick. it has made me feel more hungry more often, but im not able to eat anymore food than before. and when i do it, it hurts really bad and i feel so sick like gagging im so nauseas. after my first dose, i ended up eating too many goldfish (like 30) bc there was this weird grace period of a few minutes between sick and i thought wow erythromycin is working, but nope. i was too sick to speak the rest of the night, and even though im not overeating anymore, i am still so fucking sick. i plan on calling my doctor tomorrow to ask what i should do, but i think id rather not be hungry and not be as sick when i eat its terrible. did anyone else have these symptoms? do they go away? also, i haven’t found a nausea medication that works for me. even zofran does nothing, i can’t take reglan, and i don’t think phenergan worked much either.
