Not sure if you've sorted this out or not as it was a while ago.
I have had 3 "seizures" 2 of which were related to alcohol. Doctors told me they were environmental (not enough sleep, alcohol, anxiety related). So i was put on anti-depression meds (efexor-xr). This didn't help me in the least.
1st seizure...fair enough i'd had alot to drink, and it was the next day i was nauseous (as expected) and bloated. Had diarrhoea symptoms, and then seized in my car....luckily wasn't going anywhere.
Tests showed nothing.
2nd time, only 2 beers. Same feelings the next day and i made it from one end of the house, to the bathroom to wash my face, to the other end of the house without knowing i was doing it, and collapsed on the floor and seized.
tests showed nothing again. Full blood tests, epilepsy (eeg, mri's etc) liver function...whatever...even had endoscopy and colonoscopy to check out my guts for anything GERD like...100% physically healthy i was!
3rd time later after 3 years seizure-free, i was watching a movie and felt the familiar warning signs...then bang. had another one. No drinking involved at all as it makes my guts bloat up straight away. so off to the specialist again...this time i had some drinks the night before my eeg to try and get worst case scenario happening. and what do you know. They finally picked up I have epilepsy! Also turned out a majority of the times i was sick (bloated/nauseous/dizzy etc.) were mini-seizures.
Now on epilim medication for epilepsy. Just have to treat my anxiety somehow. (going 7 years with ppl telling you you're healthy when you know you aren't has an effect on your head after a while!).
Apparently the tests only pick up epilepsy 4 times out of 10.
Whether this is what you have or not...? Sounds somewhat similar to what i had though. Worth mentioning to your doctor to get a referral to a neuro specialist.
