Hi Alana, I've been off for a while due to holidays and generally not beig on the wagon so only just caught up with everything properly....
Firstly.... Well done you for getting back on exante even with all the migrains, i have never had a proper migrain but they sound HORRENDOUS! Please never ever beat yourself up about falling off plan when your suffering, it is just one of those things and you would have to be made of stone to not fall off when feeling so awful!!!!
Secondly... You need to do what it right for you, as the lovely Lanarkwitch says, you sound like you know WW inside out and if you do that for four ish weeks and get your proper diet head on you can then take a step back and assess how you want to continue, it will be easier tk maintain loosing weight via WW, although slower, i am an "I want it all and I want it now" kinda gal do exante suits me but it's ll personal preference and only you know the answer to what is right for you!
Thirdly and finally.... You and your health are more important than any diet will ever be!
Be happy and be healthy!
Muchos love (still in Mexican mode)
