no harm done, IMHO. One has to do what one is comfortable with when you will not be home to monitor. I am sorry that you had a rough weekend. I too am surprised at their dose recommendation. I just think it is/was too much. I truly believe that you can trust what you read here - these folks have alot of experience, and are very knowledgeable. They have literally gotten us to where we are today, and I am grateful. We went through 1.5 years of vet recommendations before i found this board. during that time we had 3 hypos, a bunch of other stuff. since being here Mannie is doing so much better - these guys do know their stuff.
Try not to worry today - it is a great amps - you did what you felt was right.
