I've been using the VWMC center for about 2-3 weeks. As a faux-vegetarian (rarely eat meat), I thought I'd supplement my nutritional needs with B12 (something that can be lacking in a diet w/o animal meat or protein) once each week. The B12 combined with adequate rest has served me well. The staff is friendly, the office is quiet and calm, and the actual injection can barely be felt at all. I'm feeling good and only wish they would advertise with Groupon or the other "deal" sites!
