plateau?

It's been a while since I've posted on here, but I need to get back to it. I am 5 months out and down a total of 118 lbs including my pre-surgery loss. I feel so much better and I get around so much better too. The problem is that I still have just under 150 lbs to go to goal weight and I seem to have hit a plateau. My doc took me off my water pill so I think that is where I gained the 5 lbs back. I've been between 316 and 322 for the last 2-3 weeks. I'm trying to get below the 300 mark by my birthday (july 27) but now I don't know if that's going to happen. It will be so cool to weigh two hundred something instead of four hundred or three hundred something. Well, I guess I should stop talking about it and go eat some fat free yogurt and go out for my walk.  Oh yea, I also wanted to say that I can now walk all the way around the track when previously I could only walk from my house to my car without getting winded. Maybe I'll walk on the beach today. Probably not, I need to work on cleaning the house today. My daughter and granddaughters have moved out and my friend is getting most of her stuff out, so the house is easier to clean now. Need to groom the dogs today too. Busy busy, but no excuses-going to do my walking first.
