Meg,
You are going to have so many wonderful things happen to you in this journey. Put Onederville out of your mind. It's just a number. Make a list of all the things you want to do along the way and tick them off as you can. Maybe you want to ride a jet ski, or go parasailing, or ride a rollercoaster, or fly to Europe, or sit on the inside seat of a bus, or walk 5 miles without stopping, or walk up 3 flights of stairs without being winded -- whatever your goals are.
That said, before you know it, you WILL be in Onederland. The first year being banded flies by. Sitting here today, I can't believe this is my 4th year bandiversary. Four years! I checked off all the things on my list nearly 3 years ago! I had my tummy tuck more than 3 years ago. Wow, that's amazing to think about. I've been gone from LBT for a long time, so today is the first time I'm really thinking about these issues in a while.
My advice to you is to cherish the experience. The 200s are full of great joys. You rediscover your physicality in the 200s (at least I did). Everything becomes easier. Then when you get to 249, you think to yourself "gee, I can't BELIEVE I'm closer to the Ones than to the Threes!"
As for plastics, Sandi is absolutely right that most doctors recommend waiting 6 months at a stable weight before having them. I'm a perfect example of why. I had a tummy tuck at 195 lbs. I didn't think I'd lose much more weight, but I was wrong. I went on to lose 60 more lbs and I had some loose stomach skin that I had to have revised. That said, I don't regret the first TT when I had it! I always tell people anecdotally that I lost 200+ lbs in a little over a year, but I went from being a "fat" person to a "thin" person in a 6 hour surgery. It's AMAZING what a TT does for your body after 150+ lb weightloss.
The need to wait for 6 months (for most people at least) is at least two-fold. First, MONEY. Plastics is expensive. Most people don't want to pay for it twice. I have the very fortunate circumstance of having a dad who's a plastic surgeon. That is rare, but obviates the financial concern in my case. Second, and more importantly, surgical risk. Two surgeries are riskier than one surgery. I did have a complication with my second surgery (I developed seromas in my legs and had to drain them MYSELF for about 6 weeks - it was awful). I wouldn't change the way I did it, but my circumstances were somewhat special (it being free and me being in "marathon" shape and in my 30s, thus, fairly low risk as far as surgery can ever be low risk). Waiting for goal does make sense 99/100 times.
Hang in there. Time is going to fly, I promise.
