... sleep in the first three days and 5-6 hours between the last 4 days today is the 7 th day and I was feeling great well all the sudden I was very sleepy head felt like it was swelling and it was throwing took my B's and it was 590 ( no ketones ) now very bad headache swelling feeling has seemed to go away a bit. I'm not tired just not sure if this is HHS feeling clay and have a headache and arms feel heavy. Is this just a case of not enough sleep?
