I've been on OO cap's for 3 weeks and inhaled OO for 2 weeks. I've seen a drastic reduction in mucus production. Seems like I can keep up at aerobics class better without getting as winded and I don't cough as much when exerting. My general day in, day out cough is about the same. My sinuses have bled for the 1st time in my life in the last month - only presents when I blow my nose so it's definitely clotting fast. Probably not related but thought I'd mention it. I feel good. I sometimes do 'practice' pfts and I feel like I am doing better than my usual. I'm excited to go to get my pft's done in ~6 wks. I'm definitely sticking with it until I prove it not good (for me) or someone else does. The last two days it's been a bit burning as I inhale it - might back off to 3 drops. I've mentioned on another post that I new bumps on the roof of my mouth. Some have suggested this might be thrush. Could be my new CF doc. puts his patients on Bactrim to fend off bugs - says it's an umbrella. This practice make me uncomfortable but I haven't gotten sick while on it so maybe it is killing intruders. I also got bad fissues down there and started taking acidopholis pills 2x/day to help keep the good flora around that the Bactrim is killing. I don't this would be necessary with only the OO. I'll find out soon because I don't think I'll keep doing the 'umbrella' drugs for much longer. Anyone else on pre-cautionary oral antibiotics?
