Sugar crash symptoms and conditions

I'm on my sixth week of Levoxyl 50 mcg. I've been feeling great, and even losing some fat. I've been able to work my 14-hour Mondays without any caffeine at all as well. My pancreas must have been stimulated to work more efficiently, because I don't wake up hungry, I don't get the sugar crash and shakiness before meals, and I can go longer between eating without feeling homicidal.

The only weird thing: my lips are extremely dry. They're cracked, chapped and swollen so much it looks like I had a lip job. Even a tiny bit of salt hurts to eat it, as well as wine and spicy food. IDGI.
