I concur, with what Roger is saying. Wasn't looking for, nor even thinking about it. Since I've been using the RezBlock, my consumption has gone down. I haven't needed to medicate as often. Not Earth-shattering savings. But its been significant enough, for me to notice. I even setup a small test between my Box (which always gets me medicated with two good pulls). Still getting the same results with it.
My HI, I would always vape at least two tubes. Always. I wouldn't ever leave a tube unfinished. Never.
I'm not even finishing my first load, sometimes. If its later, instead of the 2 or 3, I might vape in the evening... its 1 or 2. The other day, I realized I went the entire day, only medicating twice.
I didn't say anything, because I thought my medical condition, tolerance, whatever was just acting weird. But, it definitely correlates to me using the RezBlock.
