You can definitely do it! Now I do know that everyone is different, but I started SW the same weight is you, and as of my 5th week last Tuesday, I had 12 pounds off!
As willfitskinnyjeans said, you should try your best to totally avoid any events coming up if it is at all possible.
Other options are to try switching plans for maybe every second or third week. I'm on extra easy normally, but after 2 weeks of losing 2lb, I did one full week of Original and lost 3 1/2lbs!
A lot of people will tell you that, while exercise does help, doing the same exercise will eventually not be enough. You need to either change the routine entirely or up the ante so to speak. Something as simply as taking a different route when cycling to work, or doing your usual gym workout backwards can really change things! Maybe also try a small workout at home on top of your gym workouts. I'm doing the 30-day Squat Challenge, and as I find squats ridiculous looking, I do them daily in the mornings while waiting on the kettle to boil! You'll find, once you get to day 3 or 4, you will use every mind trick you've ever seen on TV to get that kettle to boil!
Another trick I've learned to manage with, is saving my syns for night time. I was having a delightful can of Coke Zero or a cup of tea with one finger of a Time-Out or 3 chunks of Galaxy Caramel and either a packet of Velvet Crunch or 21 crisps from the Special K Cracker Crisps (4 syns). Having the same at lunch time always meant I still wanted something at night when I was flaked out on the couch, but keeping it until then put some manners on me!
I'm one too!
