never/regularly/sometimes
always​

Answer 1

Answer:

never

I think this is correct answer

Answer 2

Answer:

The correct answer is sometimes.

Explanation:

The completely correct statement will look like-

I sometimes sleep for 12 hours in the weekends, if I have no errand to run.

In this statement, the speaker is telling that when he has no errand to run on the weekends, he, sometimes, sleeps for 12 hours just to relax a little bit more because he gets tired from the hectic schedule of workdays of the whole week.

This statement is grammatically correct and makes practical sense.

So, the correct answer is 'sometimes'.
