Definitely I'm worried. Drinking SN seems at least less frightening than some other methods but, I don't think I'll really be able to convince myself that I'm not just about to take the most enormous risk.
Plus, SI of course. Not sure how strong mine is exactly. It's very strong if I perceive immediate threat though. I've taken risks in life where I knew I'd be able to rectify problems but, it being so out of my control troubles me. Plus, the worse case scenario is almost enough to put me off all together- failing but seriously injuring myself.
I feel like I should have an easy backup method prepared but, I don't feel comfortable/ confident with other things. So, it's all a worry really.
