I wanted to give this thread a bump, since it seems like so many of the posters here have had quite the same experience I have, and it might help others like me who have not seen it before.
In my case, my sugar has always been "funny" since I was a kid.
Since I quit drinking, my sugar has gone somewhat more out of whack. My heart races (adrenaline response due to low blood sugar), I feel shaky but sluggish and really clumsy. Sometimes there are palpitations as well.
Also, my blood pressure has been high and I think (hope!) it is related to alcohol and tobacco use and will drop over time.
In my own case, I have a bit of GERD, too. It's quite distressing, since I'm a young-middle-aged male, and the pain is from the center of my chest to my left elbow! I'm taking a prescription antacid (a proton-pump inhibitor) but it does not always help.
You know what does help? Prune juice. Dunno why.
