I did that once and got like a chemical burn on my tongue, would be better avoided. I usually capsulate my doses, though if you want it to come on slower you can dissolve it water and drink it over the course of an hour... I couldn't taste 120mg in 500ml. Another way would be to make a bunch of 20mg capsules, and take one every 15 mins or so til you reach the dose you like. It gives the nice slow come-up of 'dabbing' it and avoids the burning.
