Talking to your Dr. is the best thing to do.
But I thought I'd share that I've experienced some of the things you mentioned. I'm not on any of the meds you're on but I've been on a variety of other drugs over the past month or so: Prozac, Xanax, Benadryl, Herbal stuff, Alcohol, Alertec...
I can tell you that I've had sensations where my brain felt like it was shifting around in my head and things got dizzy for a moment. I've also felt spacy and text has jumped around for me on the computer. It never freaked me out because it all seemed like one of my meds was causing it. Some of these drugs really mess with your hydration levels so remember to drink lots of water.
don't worry too much and give your Doc a call!
