0 Hi,02br
00I'd say that if you use the present perfect (have slept), it sounds like you haven't slept much in the past four days. Now it's time to make up for lost sleep.02br
00If you use the simple past (slept), you might be referring to the past few days (so it would be the same as with the present perfect), but not necessarily. Maybe you are talking about an occasion

0Thanks for your reply, Clive. I wonder with context provided, will both convey the same message ? For example,02br

00I feel terrible now. I have only slept 3 hours in four days02br

00And are both version likely to be said by native speakers?0-

0 I hadn't seen Clive's reply. 02br
00Well, as for your second question, I'd say both would be ok, according to the "American theory" that says the simple past is always ok in 90% of all the possible past contexts. 05002br
00New let's see if the natives agree. 010id1

0Thanks Kooyeen and Clive. Kooyeen, I didn't see your post when I replied to Clive. We must have been replying at the same time but it took me longer 050010id1
