1 I'm always drinking like crazy when I see her. The meaning: I start drinking and after a while I see her.
2 I always drink like crazy when I see her. The meaning: At first I see her, then I start drinking.
So far so good. But when I use the same model with "go", it feels like they don't work the same way.
3 I'm always drinking like crazy when I go out. The meaning should be: I start drinking and after a while I go out. But I think it's not the right meaning.
4 I always drink like crazy when I go out. The meaning: At first I go out, then I start drinking.
Do you agree that 3 breaks the rule which is there in 1? I think that 3 means the same as 4. If it's so, can you explain why? Something to do with the verb GO?
