333 should be a strong trip. How come 333? It seems like kind of an odd figure to be so exact, unless you're thinking to take 333 seeds since 333 is an important number in numerology. Aside from the mystical side of the number whether there's any truth to that or not, 333 should be a pretty strong dose if you aren't doing a CWE. If you're doing a CWE, it's a moderate dose but not crazy high or anything. Chewing the seeds is significantly stronger and I'd expect that you'd trip pretty hard from that dose. You will likely vomit during the trip or at least feel quite nauseated though eating that dose, particularly as you aren't doing a cold water extraction. As far as I know, the cyanide thing is a myth but the seeds contain various nasty chemicals that make you feel rather ill at points during the trip but aren't really dangerous for most people. If you have a little something to eat beforehand, it may reduce the sickness a bit. I did them a couple days ago and although I felt like puking for a few brief moments, I generally didn't feel sick at all since I ate before I took them.
