If the question is, "is this your personal experience?", for me the answer has been "yes." Adding the statement "Something similar happened for me, and this was my personal experience." does not add to the answer.
I'm totally on board if the language of the answer reads like something is suspected to be throwing spaghetti on the wall. E.g. "why don't you just try ..." That's not definitive, but might add to the spider sense that it's an off the cuff suggestion without much experience driving the answer.
