Response:

The deep sleepy state that you sometimes have in meditation is perfectly fine. 

Your mind/body is getting exactly the experience it needs at that time. 

If you need to take a little longer to come out of meditation so that you feel ready for activity, then take an extra minute or two. 

It just means that the release process is still finishing up. 

If you have the opportunity and time, lie down for 5 minutes at the end of meditation to let it fully release.

Love,

Deepak
