I use the stuff.

I used to run marathons - I took a bottle of the stuff about half way. Maybe it was reassurance, maybe fuel, but it worked for me.

As a T1 Diabetic, when I get the 'bonk' (hypoglycemia) it's important to get something in the system fast, and something that isn't fussy or hard to choke down. This stuff works for me. Usually have a bottle in the jersey pocket
