aww!! I hope you feel better! I can't really give medical advice, but perhaps advice based on what I've read/learned from experience will help. First- it's great that you're taking the Vitamin C. I had a short cold during December & the doctor told me that once the infection has attacked your immune system, it's up to your body to work it out & fight it off. The C might not do much at this point, because it's more for prevention & getting your daily supplement of vitamin C. Once the cold hits, the C won't give you an extra boost to fight it off or anything like that. Just FYI. Although I take extra too when I'm sick, haha, so that shows how much I listen to my doctor
I would keep taking Aiborne or Emergen-C, that will ward off any other infections that could get to you while your immune system is in overdrive. I think the golden advice when you're sick is to get ALOT of rest- at least 6-8 hrs of sleep every night, & take it easy during the day; if you work out, take it slowww or take the time off & just stretch/walk. And ALOT OF FLUIDS!!! keep drinking water throughout the whole day!! If you do these things while on the antibiotics, you should start to feel better in a few days, a week at the very most.
If you are not feeling better by then, I would question what antibiotics you are on & what type of sickness/infection you actually have. I think medicine for the flu or for a common cold, or for a sinus infection, whatever it may be, all require different antibiotics, so ask you doctor if he/she has an exact diagnosis of what you have. When I get a sinus or respiratory infection, my doctor always puts me on a Z-Pac (Zithromax), and i get better. Just some info.
I don't know how helpful this was, but I REALLY hope you feel better! Feeling crummy is the WORST, so get well soon!
