For ME, I can't speak to you OD, but I've never had a cold move to my lungs that didn't require antibiotics to clear it up. I have chronic sinusitis and once it migrates to my lungs it is only a matter of time before I have to take antibiotics to clear it up. I know others that aren't in that boat, they can recover without them, but once I start coughing up any liquid for longer than a day or two I know I need something to help me out.
That's my position, like I said I know others that don't need them. My track record says otherwise.
Bad move Bro' Take all anti's as prescribed. If you use them later the micro bial builds up an immunity from the previous medication. This is what any doctor will tell you regarding the use of anti's that are not somewhat specific to the virus bug at hand. I've tried like many others and it's never worked for me. My mother alway's had a bottle of Tetrocycline and insisted that I take it, but It nothing for me.
I'm a believer in "frying" the bug by letting the fever break it's self and plenty of liquids and chicken noodle soup. Although If I had any higher a fever I would have sought out medical attention immediatley.
The last time I developed a fever it was 103 degrees at one point. I simply sweated it out, shivered a bit and it finally broke and I did not need to see my doc.
That's just my experience with the last bug I had back in April of this year.
