First post... but I've been lurking for awhile!! I'm scheduled for 4/18 and feeling all of the "normal" feelings: nervous, scared, excited. Good luck to everyone!
How many calories are you eating and how much are you working out? It may be possible that your workouts might be sabotaging your weight loss at this stage if you are not consuming enough calories for your energy expenditure (there's a recent thread about this if you do a search). I'm 3.5 months out from surgery and have lost 50 pounds post-op - but over the past 14 weeks what usually happens is the scale will not move for 1-3 weeks, then will suddenly drop 2 or 3 pounds several days in a row. This has been a consistent theme since surgery and I've just realised that this is how I lose weight. I no longer use the word "stall" since clearly I'd have to go much longer (for a month or so) before I need to start getting worried (but hopefully that won't happen for a while). Your body too is still coming to terms with everything, it will start showing a pattern soon enough I think. Also, averaging 5 pounds a week is really good - that's almost a pound a day - just keep at it.
