My boss swears it makes you crave more sweet stuff but tbh I find myself needing it on odd days but am fine for the most part - I think it is okay if you don't do it day in day out for ever and ever.... Also might be interesting point - when I used to take sweetner in my coffee I found myself taking more and more as time went on till I had three in each cup of coffee - my boss nagged me till I decided to go without and now I can't bear it at all in coffee - but when I was taking it I did feel the increasing need to add a bit more!!! Don't know if that is helpful or not!!!! Nowadays I just have what I need and want and don't worry about it though it isn't excessive anyway!
