Nontoxic Drywall Mud

I need a nontoxic drywall mud, quick! Someone had told me the Kerabond would be a good choice, but after mixing a little I realized that it's a sandy grout, ONLY for use with tiles. (By the way, it's totally safe for me! Now I want to do a tile project!) Anyway, some workmen used Murco here a few years ago, but I had a bad experience with that. Any suggestions? This time I'm doing the mudding myself (it's just covering a few seams.)
