Hi MM, nice to meet you. I love your avitar
First, I would let a doctor diagnose you to see if you have fibromyalgia and not your sister (I know you love her but..). Also, talk to your doctor about the restless leg syndrom and have him/her suggest a diet plan for you.
Have you ever tried Weight Watchers? I don't know about LA weight loss but when your on WW you can eat basically what you want but portion control is a big part of it. I believe thats why so many folks have good success with WW, its cause they can eat what they like.
I understand your frustration more than you know, trust me. Just hang in there and keep trying. The thing about dieting is to find something that works for "YOU", something you can live with.
Hugs !!!
