I, by no means am an expert. Neither do I have Sibes but I do have a very high maintenance, energetic, demanding breed.
I have also just gone/going through the puppy stage after 10 1/2 years, so it did come as something of a shock again. I also swear that none of my others were ever as noisy and demanding as him but I have been told that I was viewing them through rose tinted glasses lol ;-)
My first impression is that you need to get him into a routine. Easier said than done, I know. You need to decide where he going to sleep and stick to it. I also crate train and my latest addition slept, from night one, in his crate, in my bedroom. I didn't move him or let him out, regardless of the blood curdling howling and throwing himself around. Apart from toilet breaks every couple of hours, a nice blanket and teddy bear for cuddling, this was all that was offered. I had him situated by the side of my bed and would talk often to him in a quiet voice when he was distressed. It was exhausting for those first few weeks and I felt like I had a new human baby all over again. It is very hard to look at the bigger picture when you are sleep deprived...I really do sympathise.
I fed him and let him play in his crate throughout the day and leaving him in it for very short amounts of time, for example when he was sleepy or when I had to pop out quickly, in which case he was also left with a stuffed kong. Nighttime routine was he had his last meal around 7 in the evening, toilet time, playing, toilet time, a small treat after I put him in his crate around 11 and then lights out. It took him around 10 days to acclimatise but once he knew what to expect and where he slept, then all was calm. They absolutely thrive on routine and the quicker you can enforce it, the better they will be, in my experience. Don't give in when he howls. If you know that all of his needs have been catered for, I.E. toilet, food, drink, he's not too hot or too cold, then he needs to learn to settle himself.
You know that it will get better but it takes time.
I hope this may have helped and I am sure that you will get plenty of other good advice. In the meantime, hang in there, it does get better and they are pups for such a short amount of time. My boy is now 9 months old and he has come such a long way, although at times it doesn't feel like it Lol.
