I'm dry right now... so sore.
I came dangerously close to running out a few months ago. My supplier got in a bit of trouble and it just happened to be right before I was going to replenish the stock. I was smoking on shake and roaches before I found some more.
Since then I have been keeping a pretty hefty backup sack. Just for peace of mind lol. Now if I no I can't get any for awhile I can cut back and conserve. But I won't run out.
Hardest part is keeping it fresh. Nothing worse then it drying out and crumbling to dust.
