Scheduled for November 21

I am finally scheduled to be banded on 11/21/07. My insurance required 6 months of nutrition counseling, from which I am proud to say I lost 50 pounds. Now I am going through 20 gruelling days of liquid diet to shrink the liver...yuck!! Today completes day 5 of 20 and I have been 100% compliant. But I am very sick of Atkins shakes, non fat yogurt and sugar free jello....(why dont they make this stuff in bacon or terryaki sirloin flavor?). Anyway, I have lost another 10 pounds in the last 5 days. At this rate I will be down by a total of 70-90 lbs before the surgery!! unfortunatly my glucose around 80 is dipping into the 70s...its taking juice about every 2-3 hours to keep it above 80. Does anybody know how low you should let it go before taking action?
