Could be that your body wants more. I had a similar situation while being treated for chronic pain. My body built up a big tolerance to the medication. Then before you realize it you need more and more. I noticed my body and mind will try to trick me into increasing / chasing for more and more. I did my own detox ....which is a little sadistic.... to reduce my tolerance.

I have always suspected I was ADD and finally am being treated for it. I notice the same thing in the morning. I read that it is good to take "holidays" off from the meds to help flush your system. The only problem is if you take these "holidays" you may not be very productive for the first few days. So it can mess up your work performance. It is a catch 22 for us.

Hope you get through everything!
