You know what, same exact thing here. My brain fog/reaction time was drastically better. Only on abx for 4 days when it seemed like the sun came out.
I fly RC planes...since I've been really sick I have no interest and I couldn't really react in time...especially for my heli's. Once I seen the sun break thru the clouds (my brain fog lifting) it was a huge inprovement in my reaction time... and yes, I was feeling a lot better.
Since I upped my dosage of abx I've been hurxing since...and haven't felt as good as when I was just keeping them at bay.
Not only that but I could actually concentrate on what people where saying more, and concentrate on work. Its unbeleiveable what this crap takes away from a person.
But nahhh...nahh... its just anxiety (what the Dr's say when your tests come up negative)
