Ho ho - you opened a can of worms there...
Yup - although I never really had results with the swf some people swear by it and get extreme reactions so you're wise to wait till the week end so you can hit the pan when you need to. It's no problem mixing the salt - drink it warm and it'll dissolve no problem - about the temperature of a baby's bathwater, someone said once. You may find sucking a bit of lemon (but don't chew it - bad person!!!) helps you get it down if you don't like the taste. I got used to it. Just gulp it quick as you can cos it's not worth savouring. Then you should wait about 30 mins to an hour before you have anything else to give it time to clear your stomach. If you feel things 'shifting' inside - massage your tummy, stretch, and you should get results... Let us know cos as you can see, swf's are a point of debate on this board!
All the best
