Welcome aboard Zsadist, And Thank you brother for your years of selfless service. I was in the Navy for a 14 year stretch years ago, would have stayed to retirement but was part of the Clinton era military downsizing. I have some idea of the sacrifice you made. Is your current medical state due to a service related injury? I think you will find a new family here to help support you in this phase of your life. The best recommendation I can make is Read, Read, Read. This site is full of information for the taking so to speak. Reading through the multitude of grow journals will fill in many of those questions you have. And when you are still scratching your head, just ask the question. Someone here knows the answer.
As Faded said, scoot over into the med forums and start reading there. Tons of things to get your mind churning can be found there. And the folks there will definitely have some recommendations concerning pain relief strains. It sounds like you will need something that is either very low odour, or has a killer filtration system, to keep this off the kids radar. So just ask the guys over there. Look forward to seeing what you get up to in here.
