Navy boot camp what is it like?

I'm in the DEP program (June 1) for the Navy and my ship date is Jan 11. I am 32yr old male married w/ kids and I'm going in as a E3. I joined the Navy because of lots of reasons career, family and to serve my country but as a the days go by I'm getting a little nervous. My question is about Navy Boot Camp, Pdays, Gas Chamber and ect.. what is it like?
