My opinion is that you are missing the alcohol that came with these occasions. You cannot replace this. You must mourn the loss. Some people with our addiction problem can have alcohol at home, invite others and serve them wine. None of us can drink it though.
All of us have given up situations/friends/moments/relationships/memories. They may differ but alcohol was absolutely central to our lives; it became so important that we had to give it up.
I am sure part of your 'hosting' memories are also dreadful and you don't want to go back there. Still, you cannot have something you cherished that was linked to alcohol without suffering the loss of it.
I try to think of it as I see my past as a runner who could finish 10 km in 40 minutes. It will not happen again. I may finish a 10 km but it will be much longer and more painful and less fun.
Being sober has many positive aspects but it does not replicate alcohol experience that were nice to us.
