16 weeks was a great week for me because I was feeling good and I was headed to a much needed vacation. I also decided it was finally time for me to see a chiropractor before I went and sat on an airplane for 3 hours. I was pretty pumped I made that choice because my tailbone pain was like vanished in a minute, felt great, until we slept on a pullout for two weeks. So now I'm going to try to go once a week :)
