haha that's funny, I've actually heard of people getting and running in to walls yeah. But stories like these I've only heard from people smoking it.

Ofcoarse that's your choice, but what I recommended taking for the first time you'll be fine with. Might not even be that strong enough, which you can then just top-up by adding some more drops.

Like I said with the eye open, eye closed difference, big difference (for me anyway) I could get up and move fine, almost like normal, but to meditate eyes-closed, huge difference.

Just lay down, or sit on a chair you can't easily fall off :d  -seriously, you'll be fine, just use common sense and have no fear.
