Hi Monte,
It sounds like you have a sensible neurologist. I wouldnt increase the meds either. The 4-Day evaluations you have heard of are vEEG's. (Video EEGs). It is basically like being in a sleep lab with wires attached to your head. There are also 24 & 48 hour EEG's that can be done at home. None of them are scary and the worst part of it all is getting the glue out of your hair! lol.
