I wanted to explain my post as it's a bit unclear.  Yes, I have been getting worse hangovers with the Nal, and tried one weekend of drinking WITHOUT the nal and it was the same even though I only had two coolers which wouldn't have any effect in the past.
I went to see my doc today, who has been amazingly supportive through all this.  His explanation of my terrible hangovers is that the Nal has nothing to do with it - he says that what happens to serious drinkers is that over many years you build up a tolerance, which levels out.  Then your insides break down and the slightest amount becomes intolerable.  He encouraged me to take the Nal as it's taking away the desire for me to drink - but so is the thought of those hangovers.  Thanks for your help everyone.
According to Eskapa's book If you drink without Nal you start to rebuild the cravings, undoing whatever progress you've already made. Yes tolerance is known to change in heavy or problem drinkers and you can go through crazy spells with it. I had some humdinger hangovers with Nal, but at other times for similar amounts nothing.
