Okay, I've said I've got "flotation" issues (I float better than I sink), but over the last several weeks I've managed to lose about 5 pounds. Not much, not nearly enough, IMO, but last night was the first night I've used the tub in about a month (work's been really busy lately), and I realized that I don't float out of the seats! I think this was the best soak I've had to date! now if I could lose just another 40 or so, I'll be doing very well and need WATER WINGS!
