So am I / Me too.

00i) Mary: I am fed up with eating baked beans for breakfast every day. 02br
00ii) Jane: So am I/Me too. ( you cannot use "so do I") 02br
02br
002) 02br
00i) Mary: I hate eating baked beans. 02br

00You can use "so do I" If there's no auxiliary in the main/first sentence, and if the verb's in the present tense: 02br
00"I love reading!" - "so do I" 02br
00"John hates bacon" - "so do I" 02br
00etc... 02br

02br
00I have been away for a three weeks. 02br

00i) Mary: My favourite is eggs, bacon and sausages for breakfast. 02br

00"my favourite breakfast is..." 02br
00"so is mine" 02br
00But "me too" sounds good too. 0-
