Ivana, I've been seeing Dr. Peterson for 2 yrs. He's a wonderful, caring doctor who really wants to help his patients. I think if you are realtively young and haven't been sick a really long time...like 20+ yrs. it is more likely you can get an appointment sooner rather than later. He doesn't do "bandaid" treatment. He does exhaustive testing for viruses and immune dysfunction. I took Valcyte for 1 yr. with some good result, although not what he thought to be successful. I am in the midst of Vistide infusions now. This is for EBV (which the Valcyte knocked down), CMV & my seemingly #1 enemy, HHV6. Also have complicated immune dysfunction. Think we all have that. I've been ill over 9 yrs at this point.
