This has been happening for a while now. My doctors have always remarked that I have low blood pressure.

I take Amitriptyline. My neuro recently increased the amount from 10mg to 20mg. I had been light headed before the increase. Now, it's almost constant when I stand up (I have to stand up slowly to avoid it).

Could it be that Amitriptyline is causing this? I recently introduced Clonazepam into the mix, but the light headedness was there before that.

Edit: Actually, dizziness and light headedness are listed as side effects. Maybe I'll try reducing dose from 20mg to 10mg again, since it's the Clonazepam that is really the key in controlling the burning mouth syndrome (why I take both) http://depression.emedtv.com/amitrip...e-effects.html
