Wore off after 4 days for me! Unfortunately that was just as the Easter weekend hit, I'm not a sugar person but had relatives staying and we had a big curry on the Saturday, lots of drinks, croissants, smoked salmon and scrambled eggs Sun morning etc. and managed to undo some of the benefits of the previous 4 days!
Between that and my period starting ended up having lost 2 pounds for my first week instead of the 4 it was before the weekend, however, period weight gain will be part of that so I suspect it was really more like 3.
I was due to take dose 2 yesterday but feel so ill with period (since became perimenopausal get a lot of nausea at totm) I haven't done it yet. I'm out shopping with DD tomorrow so think will do after get back.
