I made a couple batches of this stuff using schwag and Everclear. The first batch I made I had to take 3 doses before I felt a little bit of a body high. The second batch I made I think I might have knackered. I got a little distracted and let the alcohol boil for a little too long so now I just have some damp stuff at the bottom of the jar. Is there any way I can maybe add some more Everclear to this to rescue some of it or should I just try and squeeze what I can out of it?

Also, does the mixture have to boil at 170F or would it be possible to decrease the temperature a little (say 160F or so) and boil it for longer? My stovetop sucks.
