Congratulations...
I was just about to post the exact same post and symptoms because I am going through my 2WW and I'm going out of my mind too!

BUT- I have been undergoing treatment from a naturopath (iridologist) who has given me a very strict diet (no wheat, dairy, sugars or processed foods.. basically NO fun at all and NO tea or coffee and worse, no chocolate ) plus medication to help with my liver, kidneys and stomach.. they were all apprarantly functioning well under 50%. I'm not sure if it is the treatment, all in my head or if they really are pg symptoms..

This 2WW is a killer!!
