You need to seek some professional help, you have quite a few hang ups and phobias...from insects crawling up your nose, to this? First of all...there is a simple solution to your query...if you are worried about the effect of eating a lizard or frog, then simply don't eat them!!!
What on earth has this got to do with anxiety? I won't say we eat such things in Ireland. I wouldn't eat such things in any country for that matter. But surely the forum should be left for people with more serious questions? Don't get the gist of your post at all.
