hi linzi. well. i have found it hard. however, i have lost nearly 3 stone. not as quickly as i could have as i've taken breaks for holidays and christmas and if i hadn't done that i'd probably be at target. but. i have lost nearly 3 stone. and i have done ww and sw and low carbing and all sorts of other things and never lost weight. you do have to stick at it, but the results are fast. and the more you have to lose the faster they are. you might want to choose a time when you aren't busy to start as the first week can be hellish, especially if you are having to run around as you can feel really lethargic while your body works out how to use fat as an energy source rather than carbs. and if you find it hard to do ss there is ss+ and the 810 plan, i was in mild ketosis on 810, so that's another option if you want a wee bit of food.
i would say this is the fastest way of doing things. it is difficult. but once you get used to not eating, it really just becomes normal. it's more difficult to deal with my mood swings when things go wrong because i don't have my comfort blanket. but it really does pinpoint what your triggers are. and it really does make you realise how much you ate before without noticing. people offering you something, eating while cooking, all that kind of thing.
it really is a personal choice. if you think you could do it, then i would do it. all you can do is try and see. the other thing is that it costs around £40 a week for me. but i get the more expensive things. usually it's around £35. it's a bit too expensive for me but while it's working i don't want to stop. am thinking of going back on the 1000 plan shortly though so i only need to buy 2, rather than 3 a day.
hope that helps?
