I have been experimenting. I had my sons birthday yesterday and really wanted to have a piece of cake. Well, I did. It wasn't a big piece but tasted good enough that I was worried.
Anyway, 15 min after eating the cake, I went out onto the back porch and jumped rope for 20 min. After jumping, I tested my bs and got a reading of 132. That was just over half an hour after eating the cake. At this point I was getting scared and kicking myself for taking the chance. So at 1 hour after eating the cake I tested again and I was at 124. Yeah! But I was still worried. So after 1.5 hours I tested and I was at 119 and 2 hours later I was at 114. This made me feel good that I was able to work it off at the moment but I was still worried about aftershocks. So before bed, I took the dog for a 1 mile jog. Upon waking this morning I was 101. This is higher than I have been upon waking for the last week. I have been in the low 90's and high 80's upon waking so I am assuming the cake had me a little high in the morning. I am going to continue to punish myself for the rest of the week to try and prevent any dumps but I think I got it licked. I tested after breakfast and was 112. Before lunch I was 101. I am currently waiting to test post lunch but I did 5 laps up and down 4 flights of stairs right after lunch so I assume I should be ok.
All that being said, I think my point is, if you can get some extra exercise, you may be able to clear out the hangover. I know some are more progressed and/or much older than I and may not be able to do the exercise like am but I am sure anything above and beyond normal should help you out.
I hope the more experienced will give their views as I would not want to lead anyone astray. Just wanted to point out my experience and hope to help someone.
