I'm looking for a fluid restriction cup with straw

[*kana*]

About 2 years ago I happened to run across a mug/cup that measured the amount of fluid that went thru the straw.  It had a little digital meter on the top and you reset it everyday.  I have been looking for over a month and can't seem to find it again.  I almost think it was under some CHF fluid restriction site or one of those healthy people "Are you getting your 64oz of required water a day" site.  I know this product would work great for the most of us so could you please help me find it.  I don't know the name of it or the manufacture, sorry.  Ok.....off to search the web some more! 

Thanks in advance!

it was called a digistraw and was found at www.digistraw.com  it retailed for 99 dollars

I think it must have flopped because the link takes you to a medical store now, with no sign of that product.

You are brillant!  No wonder I could not find the darn thing.  Maybe it was a good product but the price was too high.  I'd have bought it if it had worked good. 

Thank you so much!
