I think it's great that you're in a support group, and glad that the meeting went wonderful. Was it the first meeting you've been to for the group? If so hopefully now that the ice is broken future meetings will be less stressful for you. Try not to worry about a 2lb short term gain, so many things could be the cause of it, just keep working hard and sticking to your plan as best you can do, those 2 lbs will mean nothing. Sorry to hear your back is troubling you more. I think that might also be something that comes and goes, mine has been giving me fits too....good days and bad days as they say. Hang in there, keep going, you are making progress and doing good!
