No puedo hablar espanol

After encountering Spanish-only speaking patients on two separate occasions this month, I have decided that I would like to relearn Spanish and become as fluent as possible (even at my best, both my speaking and listening comprehension were pretty pathetic). I have started to read through my old Spanish text book. Although that will probably help me with grammar for reading and writing purposes, it still renders me useless in the world of verbal communication...which is precisely what I need to be able to do with my patients.





How can I improve? I've thought about getting Rosetta Stone. It's a shitload of money, but I figure it's worth it if it works. I don't want to shell out the dinero if it's not going to help me. What would you all recommend? Has anyone tried Rosetta Stone?
