I will (if my pharmacy lets me) be on the shakes until the 18th Dec, yeah. I'm intending to go all the way down via TFR though whereas a lot of people on here will be happy to get to a BMI of under 25 and do the rest themselves - hence why I'll be on it for ages.
We always say the same thing to newbies, the first week is the hardest to get through but it does get sooooo much easier after that. You know that you can do it as you got through a week last time, so that is not an issue. Your issue is going to be to stick at it throughout the second week and beyond rather than by rewarding yourself with food for doing so well your first week.
Week 1 - the toughest by far. You're dealing with being hungry as your body is not yet using it's reserves of fat and you're also not in ketosis yet. This is a very difficult time where hunger is a big issue.
Week 2 - you should have the euphoria of a great first WI to get you through the second week. By now you are in ketosis and therefore not feeling so rough but you will also still have an attachment to food, possibly for comfort. This week can also be found difficult as you are not really hungry but suffering from 'head hunger'.
Week 3 - they say it takes 21 days to break a habit, right? So by the end of week 3 you should be finding that you're depending less and less on food for comfort and learning to deal with issues in a less fattening manner. Also you should be fully and firmly in ketosis. You may still find that you're wanting to chew something but this passes quicker than in weeks 1 & 2.
Week 4 - if nothing else the fact that you have lasted so long should be enough to get you through this week. By now you should no longer be feeling hungry, you should be experiencing more energy and a general feeling of well-being. You've done fantastically well to get this far and that is what will push you forward - you've come too far to let all of this hard work go to waste!
Okay, so all in all that was a bit of a ramble but I'm just trying to show what people generally go through week by week. Obviously (just to cover my bum lol) everyone is different and some don't experience the same things that I've just written out, but I based them on my personal experience mostly which seems to be the general way of feeling throughout the first four weeks.
I'm going to shut up now as I've written an essay but I hope this helps you at least a little to show that each week you keep focused and make it through it gets easier and easier sweetie. Also, routine is the key. Develop a routine involving your shakes and try to stick to it.
Hope this makes at least a little sense...
