This only applies to the women on the forum, but I'd like to recommend using a mooncup or menstrual cup while touring, if not all the time. I am the first to admit I was very sceptical but after finally getting up the courage to try one I am totally converted.

You can wear it for hours at a time, it's much easier to clean and less messy than you'd think, never leaks, there's no risk of TSS so you can wear it ahead of time if you think "the painters" are about to arrive, takes up almost no room compared with carrying boxes around and you don't have to worry about what to do with the garbage if you're camping. Not to mention the fact it's cheaper than buying supplies every month. I wouldn't leave it at home now -- a real godsend if you are keen on 'wild' travel in remote places, where you don't want to leave a trail of garbage behind you and may not always be near shops for supplies.
