Diabetes: While the carbs in the beer were

First off, I haven't yet found the correct dosage of insulin to get my bg to a normal level I inject Novomix 30 and started out on 10 units am/pm. I eat at regular intervals and take the insulin at the same time each day (give or take 30 mins) I exercise in moderation and eat low carb meals. I'm now up to 22 units which I've upped from 10 in increments of 2 units a week over the last few months. My bg is hovering around 130 to 220 with the occasional lows of 80 - 110. I've had a few very lows [55 - 60] and suffered the usual symptoms, sweating, shaking, confused etc. a couple of dextrose tablets got me back from outer space :)

Yesterday I had a celebratory afternoon and drank way to much beer! When I arrived home for dinner I ate a juicy steak and mixed salad (no carbs) I then remembered to test my blood... It was a shocking 320! (how bad is that? That's a question :) Guess what...? I realized this morning that I had forgotten to take my insulin after the 320 reading the day before! Here's what's puzzling me....When I tested this morning before breakfast my bg was 165. How can that be possible? I'm supposed to be T1 so how can by bg drop from a high of 320 to 165 in my sleep when I'm supposedly producing no insulin? Somebody please enlighten me as all this stuff is fairly new to me.

While the carbs in the beer were, I'm sure, the cause of the rise, the alcohol in it was probably the cause of the drop overnight. Alcohol affects us all differently, and can affect each of differently each time we over-indulge. It can raise or lower our glucose levels, sometimes dramatically, for up to 24 hours. And when it causes it to drop because one's liver is busy working at metabolizing the alcohol, it doesn't pay attention to glucose levels and won't kick in to help fight the low.
