I've read about what others have done when they've fallen ill along their trek, but none of the solutions seems to fit for me. I experience vertigo once in a while. Lots of nausea and dizzyness goes with it and I cannot ride in a vehicle or walk during the episodes which sometimes last three full days. I'll do all I can to avoid/prevent an attack, but my friends want to know what to do if I have an episode. Are there infirmaries in small towns where I could take refuge until the attack passes? I'd then catch up with friends by bus or taxi. any info or ideas? Thank you.
