I asked about this a few wks ago here, cos my CDC said I didn't have to bother! But I don't think it would be formally recommended if it wasn't necessary. She also didn't advise me that I shouldn't be on diuretics at the start of the diet, which is probably why I thought I was having a stroke during the first three days - extreme dehydration headache! But I got a copy (albeit old) of the Cambridge Diet book which explains things a bit more now, and of course, this forum for really up to date and REAL advice!
Having read this, I think I will do AAM myself next week (week 5 for me).
Cheers!
