Finally Gonna Doing Something About it!!!@!

Well, I took that first big step//I joined Weight Watchers this week. I knew I had to do something. I'm off work for 6 weeks due to eye complications (waiting for surgery) and after the first 2 weeks I knew I had gained weight. So, I went. They took my height, asked a few questions and then it was weigh in time. Good Lord was it a shock!!!!! I weighed in at 197.2!!!!! That is absolutely disgusting. The lady that weighed me in was really surprised , she said that I carry my weight well. That does not matter to me...there are people on the Biggest Loser who weigh less than me!!!! Anyways, I'm happy that I got off my FAT butt and plunged in. Now is the hard part....for breakfast and lunch I do really well, I've been eating great and keeping track, but after lunch I fall apart. I get the munchies hard core EVERY afternoon. For instance, for breakfast today I had the new Weight Control oatmeal and a yogurt (fat free and no sugaradded), then for lunch I heated some left over cabbage casserole (cabbage, sauerkraut, hamburg, rice, tomatoes), pretty healthy. the an hour later I had a granola bar. now, 3 hours later i just had a grilled cheese!!! what the hell?!?! So, the snacking is my issue. Anyone have any advice? I need something that will fill me up. I do not seem to own an 'off' switch. I keep eating and eating and eating...just like the energizer bunny. I'm definitely not the nibble on veggies type, that just doesn't do it for me. I've gone over my points pretty much everyday. I did well Friday, but then went out drinking all night. ooops. I really want to succeed on Weight Watchers. I don't want to go back to work weighing 20 or 30 more pounds. Oh well. So, if anyone has any advice that is on weight watchers or has been on ww, then I would appreciate any help you can give.
