请问关于or和nor的用法问题，以下是我自己的理解：

1.not...or和not...nor...可以互换：

I don't like apples or/nor bananas. 

He came without food or/nor drinks. 

2.前面有标点符号隔开时只能用nor不能用or，理由可能是有标点符号隔开时可以将后半句理解为倒装省略句？

Spring never comes, nor summer.

I have no mother, nor any relatives.

I don't trust him—nor his wife.

3.not...nor中nor可以单独引导句子，or不可以：

He wasn't there on Monday. Nor on Tuesday, for that matter.

（这里是...Nor was there on Tuesday的省略吗？）

但是or可以在肯定句中单独引导句子：

You can choose to come with us. Or you can stay alone.

4.neither...nor和either..or...搭配不可混用（例子省略）

5.后半句倒装时只能用nor：

I didn't go, and nor did my wife.

You shouldn't work so hard and nor should I.

I don't know, nor do I care.

6.从5的例句（选自英语语法网）看，是否and nor和nor都可以用，又是否有and时有无逗号都可以，没有and连接时必须要逗号隔开？可以用句号隔开吗？

I don't know nor do I care.（无逗号是否正确？）

I don't know. Nor do I care.（句号连接是否正确？）

关于nor和or的用法要求真的有点混乱，麻烦老师一一指点迷津！感谢！！！
