I Had Some Dental Work Done Recently. I Get Anxious

I had some dental work done recently. I get anxious so my dentist prescribed two 1 mg ativan for just prior to the procedure. That was at 11 yesterday morning and I feel I am still feeling the effects...of two very small pills. Dizzy, wobbly on my legs, lightheaded, a bit nauseous and constant (mild) achy feeling in my kidney area. I had kidney stones that grew to such a size I needed surgery to remove them and am always concerned I may do something the aggravate that situation as I do have to watch what I eat.
