Hi Simon and welcome to the diet and forum. Well done you for taking this important step. The first 4-7 days can be a trial, I won't lie to you but if you stay 100% and drink gallons of water, you will be fine.
You will be amazed how quick the weight just melts off of you. I can't stop crowing on here today but I have lost 50lb in 10 weeks! I still cannot believe it. All the very best pet. Use the forum as much as you can, everyone is so encouraging, they have really helped to keep me motivated. xXx
