Trish, congrats on getting through the 5DPT!

I'm glad that you found it helpful with your beverage consumption. My partner (RNY in '05) drinks a lot of diet soda and it's been one of his struggles, so I know what it can be like to deal with...
I know it's hard to find time in your busy schedule for physical activity - you have a
lot going on now (but congrats on having a wedding and school and other really GOOD things in your life to juggle!

), but you can do it. You'll find what fits your schedule and still challenges your body and gets you moving again. Maybe some brisk, mind-clearing and stress-reducing walks while you're thinking of wedding plans would help, or stretching and calisthenic-type exercises when you first get up in the morning... I'm looking forward to hearing what solution you develop - best wishes on everything you're doing!
