Does anyone have experience with being on a magnesium drip?

I got sent to labor and delivery from my 37 week appointment this morning. They've diagnosed me with severe pre-eclampsia and are inducing me today. They've also started me on a magnesium drip as my BPs are high enough that they're concerned about seizure risk. They said I'll be pretty much stuck in bed tied to an IV pole for the whole labor now. Tell me about your magnesium experiences.
