Hi there ~
I understand your concerns. The VA is usually slow with these things and you have to go through a lot of procedures like see their substance abuse
counselor and give your history again and go through their groups and yada yada yada. They have their own "system" that they follow. Be patient but persistent and insist on getting your medications. I hope you will succeed. Having your doctor call on the doctor at the VA or the pharmacy there may work too.
I hope this helps. Take care and have a lovely day!
