I also had a B12 shot and yeah it was great but i wore off and I haven't had another. I did take a couple of months to wear off so thanks EzJim for reminding me about it. I will get one tommorrow. Yes I feel as though I could sleep forever yet I have insomimia go figure. What are they saying about Vitamin D? I came on to see how everyone was doing and came upon this and it struck home. Hard. I was looking for information on Trismus and of course I found that too. I love this site! It is my dictionary for everything I feel. I hope it is as useful to everyone else as it is to me.
