Typical or weird? (weight GAINS)

I am 5 weeks post-op, and twice now I have experienced 3-5 lb weight GAINS. The first time was random, and it really upset me. The second time was after I hurt my back and was basically immobile for 3 days as well as taking (liquid) pain meds (hydrocodone).

It is very frustrating, especially when I think that I have only lost 20 lbs (+/-) total since surgery, at a time where I thought my numbers would be much higher.

Is this typical?? Right now, I just got down to 1 lb BELOW the last 5 lb gain (so I lost 6 lbs, verrry slowly) and now I'm up almost 2 lbs.

IT'S SO FRUSTRATING!! Especially when I don't know if anyone has ever experienced such a strange phenomena. I can't call my regular doc since they are closed for the holidays.

I have to admit, I am not exercising (because of my back issues, in tandem with the stress of the holidays), and I'm hoping that this, in conjunction with my choosing high carb items (baked potato Soup, cheese soup, noodles, etc) has something to do with it. Please tell me that this is actually what the problem is, so that I can begin that rapid downward scoop that I was looking for pre-surgery!!

Or, am I just expecting too much, and should I be happy with my weight loss to date? I began at 245 which is comparatively low for GSS patients, in general (I'm told). Could that be it??

I'm just stumped, and frustrated.
