Yes I did Michael, yes I did. I use the one at the shop too! 
Better safe than convulsing!

Just cause NITROX came up!
I took my NITROX cert about a month ago. I have yet to dive with it though. I am waiting till the water here in Texas gets a bit warmer so I can take advantage of the longer bottom time. (My wife and I get cold after 60min in 65f water.) I have been debating about buying an O2 sensor. My local dive shop has a nice compressor that pre mixes the mixture so that is awesome. Anyway, best I can figure he is going to analyze the mix with his O2 stick as long as I get the NITROX fill from him. If I get air after the NITROX fill he will not analyze the Air/NITROX mix for free. I know it will be less than the FO2 of the last NITROX fill and I was planning on treating it as AIR/FO2 21% and just having a safety factor. Is this safe from a medical standpoint? It just seems like a big expense to spend $225 for the sensor. If I want to know the mix I will pay for the NITROX every time.

Never assume ANYTHING! Measure, measure, measure. Don't guess... measure. After that, I got a bit anal about how I treat NitrOx.

What agency did you certify with? NAUI requires 2 dives on EAN to certify. Not that I think the dives are the most important step in NitrOx certification; it's the prep, following the MOD, and knowledge that's truely important. The dives just aid as a vehicle to reinforce the training and to prove you understood it.

The dives were not required, so I was told.?

OK. You may want to consider diving several tanks in the near future so that you develop a routine with the proceedures on NitrOx. I like to think that familiarity and quality practice makes for a safe formula when it come to diving.

Since this has degraded, I'll nudge it back in line - the dizzyness part.
I've had that vertigo in several dives, shallow water, but they were cooler dives in dive by brail situations. Without something to orient on, and the bottom not being within hand range, my eyes focused on the small floating stuff immediately in front of my eyes. This stuff was constantly moving and had the color of lintel soup. Once back on the surface, the vertigo subsided that was the point I called the dive.
There is also that possibility of bad gas as well, and I'm not talkin Taco Bell induced.
