Wow, thanks guys for all the posts. It's been fascinating reading. I can't keep up as much I'd like in the week because I'm busy with work in the daytime, and in the evenings I'm so sleepy at the moment that it's all I can do to keep from nodding off before 8 pm. Kind of curtails things. I'm just waiting for supplements to come in the post, and my appointment for acupuncture and Chinese herbs is Friday. Wish me luck x
