Just wait til you see what I've got in store... let's just say it's *big*....  and your hubby and Ann are to blame!

Okay! Now, you've peaked my interest and curiousty .... Do tell!

You know my big aqua binder with all my info in it?

Imagine it in a digital format, complete with full text of the articles I reference and get my info from, as well as my takeaways from each one, all in .pdf format.

Also included would be "An idiot's guide to post RNY supplementation", "How to read your lab slips", and "Why you should take your vitamins -- and not because Andrea will hunt you down and force you to" type articles.

Basically, all of the vitamin posts, with citations, on a website not affiliated with any particular supplement, company, or product.

Sounds like a winning idea/blog! I'm looking forward to it.
