blaoting, burping, gas issues from juice fasting

I completed a 7 day juice fast nearly a year and a half ago. While I was fasting I felt pretty good, however after the fast as soon as I started to eat normal again I experienced really bad bloating, I looked pregnant almost. I also had a lot of belching after everything I ate and drank, along with acid reflux. The bloating since that time has imporved, but I still continue to bloat, burp and fart a lot especially at night. apple cider seems to make things worse. Ive tried taking probiotics and enzymes, but that hasnt helped.

Has anybody experience these sorts of problems after a juice fast? I dont swallow air and am pretty sure this is a result from fasting. I thought juice fasting was suppose to help with digestion not make things worse. Are theer any tests a doctor can do to dianosed what could possibly be going on?

thanks
