Mouth Ulcer 2

This morning, I took two of those Vitamin-C
tablets in the hopes of eliminating those very
irritating and painful mouth ulcers. But after
5 minutes, my mouth is still painful. And just
today, its was the worst morning I have ever
woken up to. So, I went to check in the mirror

Oh, come on! Another four?!!! WTF!

I suspect that this must be the main culprit
because on the week before, I was eating
them almost every night. It did not occur to
me until I discussed with my wife. Then it
all came back to me like it happened. A few
years ago, I had the same keropok and also
ended up with mouth ulcers but at that time,
they were minimal. OK, so this crap is banned
and now, I have to look for an enemy to give
it to......
