Lizard Spit should be all diabetics drug of choice:

Byetta (exenatide), derived from a compound found in the saliva of the Gila monster, a large lizard native to the southwestern US, is a functional analog of Glucagon-Like Peptide-1 (GLP-1), a naturally occuring peptide which enhances insulin secretion in response to elevated plasma glucose levels. By mimicking the function of GLP-1, the drug helps more strongly activate this pathway to improve glycemic control.
Tried it once, but having to wake up in the morning and kiss that lizard was hard to do. ;O)
