Lighter life again

Hello everyone,
I'm doing LL in my second week and lost quite few pounds( 8.5 ) and I've got 6stones to lose for my wedding in Sep/09..Need to talk to you guys out there for support.I've done LL before for 7 weeks but went on holiday and never gone back,sice then I've gained 3 stones and its purely cause I'm careless and started eating like crazy,no exercise and I only blame myself for that..anyway I'm back again and find it extremely difficult but my motivation is much stronger this time
