The VA doctors can and will mail them for one month so I can travel for upto 2 months without going to a different VA clinic or hospital to get a refill. I did a trip like that last year to take the granddaughter to Space Camp and am on the same type of trip again now. She did Aviation Challenge this year there and we just dropped her off home on Saturday. I am having this months mailed, the doctor is ok with it as long as I don't longer than that to see her. The VA almost always does a pee test every month, and has for years, because of the drugs I am on.
