Body Fat %

So this morning, I weighed myself and have lost 55 lbs. Only 31 to go!
My current BMI is 29, and according to the Body Fat Calculator, I'm at 38%. I think when I started this, my fat % was almost half my body weight! I think it was around 46%. Yikes!
When I look back at previous entries, I see that I had lost 50 lbs on April 28. So here it is 13 days later, and I've lost another 5. So I'm staying right on track. I like knowing that I am consistently losing that 2-3 lbs per week, and I have no problem with that. But I think I need to reevaluate some things, and work harder.
For one, I am still using too much salt. Granted, when I was eating tons of processed foods, there were many more milligrams of sodium entering my body. I do salt my veggies, and my chicken, but I could cut back there.
Also, I don't think my water intake is where it should be. My goal is 64 oz a day, and currently, I'm probably only getting an average of 50 oz. I need to make sure I'm getting a couple more glasses of water in the morning. And when summer comes, I'll need to nearly double my current intake, since I'm out in the sun most of the day.

The other thing I'm wondering about is my blood pressure meds. When my doctor prescribed my pills, I was 55 lbs heavier. At what point do you need to see the doctor and have your medications reevaluated? I currently take Hydrochlorothiazide, plus Atenolol. The first one is also a diuretic, and the second one really keeps my pressure down. But I've also noticed that my resting heart rate is around 60, and I'm not sure if that's normal. I suppose I need to get in for a check-up. My doctor can answer all these questions for me, and she'll be so proud of the weight loss, too!
