I was on a high dose antibiotic at an international meet and for a few days before competing. I was not able to sleep and wondered why? I was sick and concerned about getting sicker and my doctor suggested a double dose antibiotic to try and kick the bug before I competed. My last speed training session before the competition was incredible. I was used to feeling good but this was different.
That night I ended up going to see the team doctor as I was worried about all the tossing and turning at 4am. She did not know why I could not sleep but told me to stop taking the antibiotic. ( thanks) ( Cipro ) I am not saying I could have won that race because that is impossible to say but I crashed so bad the day of the race. I felt like absolute crap. It’s the feeling you get when the muscles have no life at all. I ended up 4th and could have at least taken a medal as the person who was 3rd was someone I routinely beat all season.
After coming home ( this meet was the Francophone Games in Africa) I learned that high dose Cipro in a very minute population takes on the effect of an stimulant. ( who knew?)
I think you need to learn as much as you can about this medication and experiment with how it effects you.
