Whilst I'm not sure on the issue of antibiotics and fatigue flare ups, I do believe that my body spends a heap of time fighting an infection and whilst I don't feel good, I generally manage until my body either fights it or succumbs to it. I recently spent 3 weeks feeling like crap fighting an infection and whilst it didn't leave me bedridden, I still felt quite unwell that whole time although with no specific symptoms and not sick enough to head to the Dr's (does this make sense?). So I agree with Quietly Here that our bodies can spend a great deal of energy fighting infection before crashing.
Having said that, I spent nearly 7yrs on and off antibiotics including spending a week in hospital on an antibiotic drip and I believe that this has been a major influence in getting CF. I now avoid antibiotics as much as possible and if I do have to take them in the future, I will be doing a liver cleanse straight after taking them because I believe they are very unhealthy for my body.
I wish you all the best :)
