Hi Joe
no experience to share but at 2 years and going well I'd be surprised if you had anything to fear
I wrapped myself in cotton wool when I first got sober and I still think it was good for me to do that...
but after that I was free to do whatever I wanted with my new entirely blank canvas of my life, without that fear I might suddenly go insane and drink.
Only you know what this job entails and how strong you feel - but don't let fear for fears sake hold you back. This is the kind of stuff we get sober for
