This is different from other canker sore posts I've seen. I've never felt like Soylent increases the chances of me getting a canker sore. Although I've seen a lot of posts of people saying they suddenly get outbreaks after going on Soylent, I've never had that problem.
However, after I already have a canker sore I can pretty reliably double the damn thing's size if I drink Soylent. If I put on Kank-a to cover the sore and then drink soylent I don't see the increase. And I wish I took pictures last time because I'm not playing around when I'm saying "it doubled" each night if I had Soylent during the day (without Kank-a). Another thing also: Soylent hurts my canker sore far more than any other food type that I put in my mouth. I find this bizarre because I expected the movement caused by chewing solid food to be far more irritating to the canker sore. Maybe since Soylent is liquid and since it is nutrient-rich something around the canker sore multiplies like crazy when it delicious Soylent (what this "something" is I don't know since canker sores aren't caused by a virus)
So basically when I have a canker sore I develop a routine of always applying the Kank-a before drinking Soylent. If I don't have it around I stay the hell away from Soylent. Anyone else have the same experience?
