OMO,
I've thought about that.
At this time, I think that may be overkill on a thru-hike.
(NOTE: My opinion - particularly related to me.)
I'm not sure if I'll be removing 2 a week or 2 in a six month period.
Visual OR physical symptoms are very rarely within 5-7 days of contracting.
With attention to the above strategy, I am planning on understanding the physical symptoms EARLY enough for antibiotics to help before it's far too serious of a problem.
I have lots to figure out though at this point. My plans will change in time I'm sure.
