Meat. I am for the last several months and likely the remainder of my natural life a pescatarian (No meat except fish / seafood). As in the stereotypical psychological breakdown, it's all my mother's fault. She cannot for some ungodly reason digest certain proteins found in meat. Apparently it's hereditary and progresses with age. For my first 17 or so years of life, I could enjoy delicious meat products. Around 17, meat starts causing some unsettledness in my stomach. I don't care, I eat away, suffering through reactions I'm quite sure Arnies is the better for not knowing.
Several months ago, I, with the help of some wonderful doctors and a procedure I was hoping to wait another 20 or so years to have, discover that the stress my body has been under from forced digestion of meat has caused a (such a wonderful term) "fissure" in my intestine.
Ok, no more meat. Now, to be completely honest, I am for the most part, enjoying my new diet. I must be more conscious of what I eat, and have been feeling much more healthy of late. However, now and again, I'll be at a friends / family member's house and someone has prepared a delicious looking spaghetti sauce which I must politely turn down.
There also arises the occasion (only one so far) when I accidentally ingest meat. Say I've ordered some cheap and overseasoned dumplings which i thought were "vegetarian". Now say my friend i was with also ordered dumplings of the "non-veg" variety. Say I take the wrong bucket and don't realize (due to the ridiculous overseasoning)until perhaps the fourth dumpling. Uh-oh. Yep, as might be expected, not only can I not digest meat, but my system has been unexposed for several months, making for a most particularly uncomfortable and intimate experience with the nearest porcelain Sir Thomas. Thanks mom. /rant
