Chemo for Psoriasis...anyone? Anyone?

So as I've made glaringly obvious, I have Psoriasis. If you don't know what it is, it's a genetic autoimmune disease in which my body makes more skin cells than it can really ever use. Seriously. I look like a leopard. I have spots people, spots. It's triggered mainly by stress and injury. And since I work two jobs, and am probably the clumsiest person in my family, I fall in to both categories. I've been dealing with it since before I knew what it was, it showed up in March and I got diagnosed in August when some cat scratches never healed up. Anywho. To make a long story short, I've been going to light treatments (UVA rays blasted at a few minutes at a time in a booth like a tanning bed only standing up and they don't tan you) a few times a week, using a heavy steroid ointment, and guess what? The Psoriasis is laughing in my face. Literally laughing. It's embarrassing lol. I recently went to my 8 week check up and my derma told me that if I don't show improvement in the next 8 weeks then I'm being put on Methotrexate, which is a form of chemo. I was like "WHUT?" I'll have to go for testing once a week for liver damage from it, mouth sores, nausea, the whole nine yards. Soooo I'm really really praying that this doesn't happen and that my body calms down. It won't exactly shut down my immune system, but it will bring it back down to normal levels. Damned overactive immune system. I blame daycare. On the somewhat upside, my dad told me he'd enjoy smoking pot with me if it did come down to me taking the drug and losing my appetite. Ha. Ha. Daddy.
