Well, I tried again today. Did it slower and let it heat up first before I even attempted to inhale. I got a decent amount of vapor and held it for about 10 seconds. I messed up a little bit though, I lost some of the vapor do to 1 cough, but it was still my most successful attempt by far.

I some some really good CEV's for about 3 minutes. Definitely not even close to a breakthru, but I know this is a step towards it.
