ok, well i've given it 21 days & i've lost 2 and a half pounds. i am actually only 5 pound off my target weight now - so im quite pleased. so did the cd do it? i'd like to think it did. i for one really enjoy listening to it last thing at night. i have found the 'evening munchies' have all but gone. my 3 meals a day are ww pointed - but it was the munchies that was stopping the weight loss. so if the cd has (in any way) helped - then in my book that is a big plus. 10 minutes might not sound very long - but having tried other diet cd's let me tell you 10 minutes is fine. any longer & you begin to 'plan a holiday etc'! i 'love' trevor's voice - so thats another big plus. the support the company gives you via e-mails is really good & there is literature you can print off and loads to read on their web site. if you are really desperate not to re-gain weight you have fought so hard to lose - then i think it's worth a go. i WON'T be selling this cd on - as i have with past diet cd's. this one is definately staying & i will continue to listen to it - as is recommended.
