Trying to get to the bottom of what for me is a new symptom - started a few days ago with oesophageal spasm and I've had heartburn pretty constantly ever since. I started VSL3 about three months ago, and take 1/4 packet a day. According to the net, some people actually take it to help with acid reflux but on the 'resistant starch' thread here on PR, apparently some people don't do well with lactobacilli. It's been suggested that I stop the VSL3, since this is the latest change I've made to my diet. Wondering what to do, and what other people's experiences with VSL3 have been.
