Tazorac and doxycycline

I used Tazorac YEARS ago for bad acne. After starting it (along with Doxycycline), I started feeling "spaced out." I can't really explain it... it felt like I was "floating in a fog." I also was having visual disturbances... kind of "snowy" vision. I discontinued the antibiotics, thinking they were the culprit, but the neurological symptoms continued. When I stopped the Tazorac, the symptoms stopped as well. I had even made an appointment with a neurologist, but didn't actually see the doctor since the nurse assured me that something I used topically could indeed cause me to have neurological symptoms. I was in denial though... thinking that maybe the Doxycycline just needed a while to get out of my system. So I tried the Tazorac again and once again the neurological symptoms reappeared. Needless to say, I got rid of it.
