I'm another snot rocket impaired person. I just keep sucking it in until I start to feel like I'm drowning, then I stop for a blow. I live for the handy tissue. Carry them by the pack and use until full and dripping. I can judge the temp by the number of tissues it takes to get to work.

Wearing my big gloves makes nose blowing a real challenge but if there's a will there's a way. Sadly I've gotten it down to a science. And while it can be a bit messy it can be done. Anyway, it beats drowned in your own snot. bikerHen
