      After 18 yrs in oil and gas my dream is to never work on oil and gas drilling rig ever again. It has taken a huge toll on my body and on my mind. Destroyed every relationship I’ve been in. The guys who have committed suicides and Drug over doses is number is so high. Good luck with you dream, don’t let it become a nightmare!
