This is a serious occurance, I would terminate using Pic and Pir immediately and maybe ALCAR.
It's possible, but "serious occurrence" was not my first thought. Piracetam has the potential to cause brain fog easily, and it's a pretty benign symptom. Also, I'm not sure about "excessive GABA" as a diagnosis, unless you mean the picamilon.
My first thought would be to drop the picamilon for a few days and see if it helps, though you say these symptoms appeared before you added that. Not really sure why picamilon would help these symptoms in particular, unless they're the result of anxiety. And it seems like you'd be aware if your anxiety suddenly increased enough that your verbal fluency took such a hit.
Piracetam can lose efficacy over time. You may want to take a break from it for a few weeks, to see if it helps restore the effect, or at least take a day or two off every week or so. Piracetam's relationship with choline can also change over time, or there could be tolerance to ALCAR, so it's no longer an effective co-supplement for piracetam (or at least, not at the tiny dose you're taking).
You might then try upping your dose of ALCAR. 300mg is very small. Personally, I take 1.5g with each 800 or 1600mg dose of piracetam. If piracetam is causing brain fog, more ALCAR can help increase your acetylcholine, and ameliorate it. I think 4g/day is the highest amount (extrapolated from rat studies) that didn't increase oxidation, so 3g is pretty spiffy. It should be obvious very quickly if this helps.
I guess it could also be a result of drinking, but the timing seems pretty off if that was a long time ago.
