I have a switch in bathroom that lights up my 25w florescent bulb. For
years I've used the up toggle switch to turn it on and down to turn it
off. Now, for the past week or so, its doing the reverse. It won't
turn on unless it turn it down. Is this possible? Its really
complicated to get at the switch cause its embedded into a large
medicine chest, and an old one at that...came with the house.

It sounds like someone flipped a 3-way switch someplace else in the
house and didn't notice it.

Think back...do you recall walking into the bathroom and saying "Who
left the damn light on?"

If so, then someone turned it on with the other 3 way switch and
didn't realize it. Find that switch, switch it the other way and
you'll be back to your usual up-down operation - until the next time
somebody toggles the other switch.
