ying 2cb for the first time, advice needed.

Sorry about the bunch of questions, I’m just trying to do my research like I do before I take any drug. Any advice is appreciated :) So I’ve done MDMA quite a lot, do you get happy like you do on MD? Usually when I take a pill I don’t eat for the full day, should I do the same for 2cb? Is there anything I should be cautious of, eg. heat exhaustion, needing to drink too much? Does it make you sweat as much as MD? Do you feel shit for a couple of days after? Does it make your pupils huge? Should I start with half a pill and take the other half when I’m at my peak or just take half for my first time? What sort of high should I be expecting? MD usually makes you feel relaxed and happy and I’m told that it can also make you see moving lights.
