Canker sores. And mouthwash.

[Jeff240sx]

Anyone else get canker sores? The only two people I know who have gotten them are myself and my friend Alan - who seems to be my doppleganger in every sense... we finish eachothes sentences, and can communicate more effectively with grunts than I communicate to others with words.
So, in the past month, I've gotten 2 canker sores, and my gf made the remark that I am "the only person [she] know[s] that gets canker sores". And I don't count Alan, because he's just me in another body. So.. WTF. Who else gets these bitches?

And mouthwash. Due to said canker sore, the Listerine had to go.. so I bought some Crest mouthwash. It went in, swished around, tingled happily and cleanly, not Listerine's burning and numbing, and then I spit. And... blue clumps came out. After washing these blue goobers down the sink, I go to google and search for omgwtfbbq blue shit. Normally that wouldn't work, and today was no exception. So, I search to "crest mouthwash clumps" and visit their site, which explains in it's FAQ:

I notice blue specks in my sink after I spit out the rinse. What are these?
The active ingredient in Crest Pro-Health, CPC, as well as the blue color can bind to bacteria and specks in your mouth, making them more visible when you spit into the sink. This is a sign that the product is working and is not harmful. Some consumers find that running the sink before expectorating the rinse helps prevent the blue debris from sticking

Apparently, the blue tongue you get is normal too. Anyway.. if you have braces - don't use this mouthwash. I've read that these clumps stick in braces easily, and take forever to get out.
And if you don't have braces, here's the notice I wish I'd have gotten: You will spit out clumps of shit for the first time in your mouthwashing experience. Man.. I'm still kinda creeped out.
