6-7mg is pretty much a threshold dose so it isn't surprising that you weren't that impressed.
A dose that small would just make me feel weird and over stimulated, without any impressive psychedelic effects. Try a 15mg dose next time and you will likely enjoy it more.
2c-i(and most other 2c-x) is more recreational and social than profound but it is still enjoyable. If you are searching for a life-changing experience than look elsewhere.
Yup pretty much what I was going to say. I'd personally go with 17-18mg for a nice light dose, but that's just me.
