I have heard mixed reviews on it (just like with any dealings with VA). Never used them myself though.
I'm using the Carrollton Clinic, where my GP is and the ATL hospital for my Orthopedic Doc. Appointments are 30 days+. It sucks.
I have used the ones in Ft. Hood, Temple TX, and Louisville. Never had any problems with setting appointments. That has been a long time ago though.
I'm not sure how appointments work in the Manila branch but I have never heard of anyone saying they have had to wait 6 months. A month is more than reasonable in the Philippines especially if you live in Dumaguete and need to make travel arrangements.
Acupuncture. I cancelled it. I have been seeing a chiropractor and a massage therapist of late. Got me back to about 80%.
