Wow! That's all the weight you've gained and you're carrying twins?! I gained that much in the first 3 months. No kiddin'! I'm a petite (read: short) 5'2" and was told to gain no more than 14 lbs. max. I was only 89 1/2 lbs. at the time. I went up to 145 lbs. much to my dr's. (and husband's) dismay. BUT! I was young and there's nothing like caring for a newborn and later chasing after a toddler to get the weight off. I doubt that you'll have any problems whatsoever w/losing weight, especially when you consider that you'll be caring for twins. You won't have time or the desire to eat. You'll just want to sleep. LOL All kidding aside, I think you'll do fine and I wouldn't worry about diet pills, if for no other reason that the one I just mentioned. They "wire" you and you'll need your rest. Stick to your healthy lifestyle and enjoy your momhood.
