After a couple of weeks on Famvir, I have gotten my first cold in over 5 years. The trouble is, it has gone south into bronchitis and I'm going to need an antibiotic - which I'm not happy about as I've spent so much time getting my gut straightened out. Any advice on what antibiotics to use and/or avoid in ME/CFS? (Other than fluroquinolones - I'll never take one of those again!). Thanks.
