Congratulations! Welcome to the fun. I am still amazed at how fast it seems to just fall off. You will be amazed at how fast you start feeling better. I feel like a totally new person just one month out. Just keep walking and sipping and you'll be fine.
I was sore like I'd done a thousand sit-ups for a good week or two. I had gas for probably a MONTH or two. But I had open RNY, so I'm sure you'll be better on both counts sooner than I was!
