No, as I had read a lot of things, and there were always mixed reviews about instant. Some people relied on it, who weren't able to tolerate the taste of regular grind, but there were far more reviews saying that instant kavas did nothing, or next to nothing, than for regular grind. So I went straight to regular grind first. I didn't want to have to guess whether or not my first few experiences were reverse tolerance, or bad product. I tried some instant after that, and it was definitely more disappointment than ordering med. grind. I've never had to toss out med. grind due to a lack of effects, but I did with two out of the three instants I've tried, which would have sent me to the bathroom long before it sent me into the pleasant state I expect from kava. (Speaking from experience here.) The third instant was from GHK, and if I'm ordering from GHK... I might as well go with micro.
