Drug guide under 1.8mb

[jeb]

Does anyone know of any drug information guides that are under 1.8mb. It's for my mom, I gave her my old palm v that only has 2mb and doesn't have any kind of expansion slots. She is a pharmacist, and will probably be retiring soon. So it's probably not worth buying a new palm for her, since this is the only reason she would use it. Mobile micromedex used to fit on there, but they have upgraded it and it no longer fits. The old version was automatically deleted because it was outdated.
thanks
