metamorphing

Last week I was a slithering reptile--all of a sudden I'm a flappy bird. This is an awful thing to endure. No-one understands that the process of metamorphosis is extremely upsetting to the system. It's hard on a worm to change shape--no less a human being. Pains in the chest, muscle spasms, and a slight feeling of nausea accompany these changes, and I don't know how long I can endure it. I have a delicate constitution.

Just a suggestion--how about making me a large mammal, and leaving me there?
