On the bus.
I've personally have had some side effects with this first shot that has increased over the last 24 hrs. Every Body is different.
My arm has gotten increasingly sore to the point of not wanting anything to touch it. I was up at 1am in pain and my entire arm felt compromised. The headache was there for most of the day yesterday. I thought I had cleared it up but for most of my working day I was a bit off. I did feel like I was hungover. Went to bed very early.
I am hopeful that round 2 is not worse. Half way there...... Half way there!
