For wet dreams, it varies from person to person. They're nothing to worry about as long as you recognize what they are and keep them from influencing your daily actions. I can't personally say much more about them, it's been a while since I had one.
Hard mode is a challenge, but then again they all are. A lot of people find the first few days to be the hardest, while others find the first few days easier, and then start struggling after a week or two. It varies from person to person, but in general you need to keep a strong resolve in order to beat your urges.
I can't add too many details, since it's so different from person to person, so I apologize there. One suggestion that I have is to start a reboot journal on the forums. There's a dedicated section of the website where you can start your own thread and journal daily progress and updates if you'd like. It helps a lot of people, and in my opinion is worth a try.
If you have more questions, there's always someone on here who is happy to answer
