My best experience on 2C-E was the first time I did 60 mg, the previous time being 40 mg, then 20 mg before that. It was amazing. I've ingested 80 mg before but I drank it too fast (I dissolved it in some water) and vomited before enough was absorbed and didn't trip too hard. I plan on repeating that with the vomiting coming later and the tripping being much harder.
