Yes, been there and it's difficult. Specially when you have to prepare food for the family and they want something different (and tasty!).
What's really important is to have a support group or friend to help. I would try to go on the program with another person and even husband if he is willing!
Get into the pantry and fridge and throw out all the 'temptations'! That's a difficult one especially with your family. Also put a 'fat' picture on the fridge to remind you if you are snacking inappropriately.
Another good one is try and find the healthy food you really like so experiment with different foods etc. I love salads so it really was good for me but there is something that you like.
Remember you don't have to cut out foods, you should eat more actually to keep up your metabolism so eat plenty of fruit, vegetables, nuts, low fat yoghurts etc. I was always grazing during snack time but eating apples, nuts etc all day. Keep a healthy snack in your bag while out and keep some nuts also. Armonds are good.
There is still a certain amount of discipline with Celebrity Slim and the first 4-5 days the toughest. You will feel tired for the first few days but keep determined. If you are not tired then it's not working. Reason is you are cutting out alot of the carbs you were having so you have cravings for the high carb diet that you were having. RESIST!
Take some multivitamins also but after a while you will get all your vitamins from the product as there is plenty of vitamins and minerals present in Celebrity slim.
Also keep on the website and look for others whom have found difficult to keep going. The forum helps in keeping motivated.
Good luck.
BTW I was on CS twice and lost a total of 14 kgs in probably a total of around 8 weeks. I felt alot healthier and alot more energy. I can now wear the trendy clothes I always missed for the last 8 years!
