Hey Fee Fee:
Don't forget that while you're away, people around you are too busy worrying about how they look than noticing how anyone else looks, so enjoy your holiday
Anyway, I can recomend slimming world, I've been known to lose about 7lbs in a week on this plan, although it varies from person to person, but the main thing is, it's focused on healthy eating and not dieting, you'll be amazed at what you can have on the plan as well! I know it might be a bit expensive to join (£10 your first week then £4.75 each week after) but it's worth it big time! Crash diets don't work and they only depress you, so please do think about your health!
If you want, you can PM me, and I can offer you some support/information on Slimming world, I honestly don't work for them but I've seen first hand what they've done for people!
I've lost another 2lbs in the past 3 days... total weight loss of 12lbs since the end of April, got another 2lbs to lose in 2 weeks

although I'd be made up to lose anything
