Hey there.

I don't take meds (DRE), and I have those symptoms from time to time. In fact, I had a very similar experience yesterday while driving. I didn't know where I was for a minute or so. Pulled over until I could get my barrings again. Doesn't happen often, (don't drive as often as I use too) so it was a little disconcerting for a while.
Bazpa also mentioned in a post that she had a strong seizure yesterday.
I came home and checked to see what was up with space weather, solar/geomagnetic activity , as strong activity can zap me without my awareness, and there's plenty of research to show that I am not alone with these experiences/symptoms. It happens to people who don't have a seizure disorder, but those of us with a low threshold tend to be more susceptible, as the research has shown. If technology can be zapped, which is why NOAA warns of these space weather conditions, then certainly it makes sense to me that our brains which are also electrical, can be affected. That's not to say that your experiences aren't med related, as I read that you've stopped taking Ativan (withdrawal symptoms?), or did for a day or so and you're on a strong cocktail. Plus you mentioned that you have gone without eating for a couple of weeks - so you may have low blood sugar. Those may be your main culprit. The active conditions in the mid and upper atmospheres of earth these past couple of days may have not help matters. You've got a lot going on there.
Here's a short, simple video I put together with some excerpts from a behavioral neuroscientist who has been doing research on geomagnetic activity and human behavior since the early 80's. Towards the end, I put a very small sampling of some studies and the side-effects of space weather, but there are hundreds of such studies. Notice in one of the studies that males seemed to be more affected by these conditions then females. This research tends to take people out of their comfort zone, but the more we become aware of our environment on the outside as well as the environment on the inside, the better off we will be in preparing for any possible reactions/interactions.
elizzza started a thread in the Kitchen about seizures and solar sunspot/geomagnetic activity. You might find some of the research posted in there of interest, perhaps.

Latest space weather forecast:
IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z:
The geomagnetic field was quiet to unsettled due to the arrival of a
favorably positioned negative polarity coronal hole.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be unsettled with a chance for active conditions at high
latitudes on Days 1 and 2 (22-23 Aug) with the arrival of a second
coronal hole high speed stream (HSS).
