Noss, sorry about your surgery. Can they fix it? That is a bummer!! I feel really sad for you, and I hope your eyesight improves!
I did something really stupid a couple months ago. There is a flower that grows 6' tall named Amaranthus, and I have seeds for it. The entire plant, including the seeds is edible. Something came up that looked exactly like it. I figured it was a seed the birds brought. Every day I tasted a leaf. Nothing bad happened, so one night I sauteed a bunch of leaves like spinach. Delicious! BUT JD was watching TV and I'm on my computer. After cleaning my glasses several times, I said "something is wrong! I have double vision." JD had it too. Pretty soon we couldn't walk without hanging on to something. Muscle cramps. YIKES. Went to emergency, and I had tried to poison us with Indian Tobacco. Who knew? The symptoms lasted for about 24 hours, but that was no fun, and I feel for you!
