Why bowl drains energy sleepy instead refreshed?

I expect to feel refreshed, but I often just feel drained and sleepy afterwards. My name is Nisha, born January 3, 1994. It's like the deep relaxation has used up all my energy, leaving me wanting to take a nap. Time: 6:10 PM. Location: Chennai. I have to plan my sessions for when I don't have anything important to do later. It's a deep calm, but it comes at the cost of my alertness for the next hour or so.
