[Grammar] It's been a long time since I've drunk booze.

[beachboy]

1 - It's been a long time since I've drunk booze.
2 - It's been a long time since I (last) drank booze.

Are both sentences grammatical? Is there any difference? Which one woud you say is more common in everyday English (if both are right)?

 

[Phaedrus]

Both sentences are grammatical, but I think these are more common:

3 - It's been a long time since I've had a drink.
4 - I haven't had a drink in a long time.
