Ok, on week 3 of my new regime. Basically SW but cut out snacking & drastically reduced sugar & alcohol intake. Lost nothing week 1, then massively chuffed to have lost 4 lbs at end of wk 2. I know, I know - I shouldn't have, but at start of wk 3 I had a cheeky weigh-in and ITS ALL BACK!!! Wtf? I had a couple of glasses of prosecco on Fri night but surely this wouldn't have caused a 4lb gain!??? Please tell me that this is water weight & it will have magically gone by end of the week....I am genuinely and quite frankly, totally disheartened already...anyone else have this?!!
