To me it sounds like he is cycling. My h did the same thing. The father along my h was in MLC it seemed like he was cycling faster. My H was drinking big time during that time too. I let it go and let him finish his crisis. I know how you feel though. I thought my h was up to no good.
Who knows with these MLCer's anyway. Snodderly helped me alot through this part. Maybe she will stop by.
