Hi Meagan!
I'm a newbie, too! I just started my "lifestyle change" today. I refuse to call it a diet because I fail miserably at diets. I have about 200 lbs to lose to be a healthy wait. What a daunting task!
I had gallbladder surgery last January, too. I ended up having a stone sneak out and lodge itself in my liver duct which made a simple procedure turn into a very complicated one. I can completely relate to the symptoms you have after eating certain foods! I can never be too far away from a bathroom if we are eating greasy food. It's embarrassing and frustrating, to say the least.
If you are looking for a motivation buddy, I'd be happy to be yours! I need some extra motivation too as my family isn't all that supportive either. My husband knows I am serious about this, but he still put a bag of Peanut M&M's in front of me tonight. Meanie!
Anyhow, good luck! You can do this!!
