I was locked in place and became infinity and was tortured for like 10,000 years as I saw the last moments before singularity, with rippling interference as the singularity grew and reality shrunk in chunks and waves. Everything stretched thin before me as I saw the undoing of all, and then suddenly I was in my bed with my cat, sticky with dried, melted ice cream cuddled into my arm.
Also I dropped the ice cream and the cat ate it 
The most I've had was maybe 20 mg and that put me on another planet, I don't think I want to do 5 times as much.
