I have only been filling like I have been so drowsy and lethargic all the time since my doctor started taking me off Clonidine. I have a Codman infusion pump and my doctor added Clonidine to my pump to assist with pain and spasm control in May 2011 starting with 12.5 micrograms per day. By October 2012, I was on 37.5 micrograms per day. On February 6, 2013 my doctor started reducing my Clonidine from 37.5 micrograms to 25 micrograms and I started becoming totally exhausted and lethargic all day long and if I eat anything, and it doesn't matter what or how much I eat, I start falling asleep with so much drowsiness that it is like someone has given me a shot to knock me out I can only stay awake to drive or do anything by drinking lots and lots of coffee. I have even fallen asleep waiting at a red light. I wake up totally exhausted and lethargic and can’t get rid of it. Sometimes I don't even realize I've fallen asleep. I never had this before not even when I started on Clonidine and now I am worried. On March 4, 2013 I was reduced from 25 micrograms to 12.5 micrograms and I still am fighting to do anything all day. Unless I drink coffee all day now, I will pass out. What is going on.
