I agree, get a noise machine and put white noise on full blast, and ear plugs too. Your kid has learned to get a certain response by screaming, and it's just going to get worse if you don't start telling him No. It sounds like he's having some control issues and a lot of frustration. I read that a child who is out of control like that may be unhappy because they don't know where the limits are and who is in charge, and they want you to be.
If cookies and sweets are a problem, don't keep them in the house at all, or keep them totally out of sight and don't give him cookies anymore. If getting into things is a problem, then box up and lock up all the problem items. It won't be forever. If he throws toys, take it and box it up for a week. You can't reason with a toddler. If he gets out of control, tell him No and walk him outside and maybe take a walk around the block.
When my high energy high spirited daughter is cooped up in the house all day, she gets completely nuts. She gets into everything all the time. We worked out a nice routine, which kids like and need, but we break it up by having little things to go do outside the house. We take a walk, go to the park, walk to the store even if it's just to buy one thing. There are lots of free things for us to get out and do, and often, just a change of scenery is all it takes to put her in a better mood.
She also gets really tired of me, and really wants to interact with other kids. This is harder, because all the other moms went back to work ages ago and their kids went to daycare. We found a parents group that meets once every two weeks, we're signing her up for a very inexpensive music class with other babies, and are always looking for opportunities to get her out with other babies.
We don't have any family here either, so it's all on me, and believe me, we can't have my husband tired at work either, so I run as much interference as possible.
