I am the same way. I tried that awful VSL and I swore it worked but I was on an antibiotic the same time, tried to transition. 2 weeks into that and Align I had horrible bacteria infections that I had to go back on Omnicef (best antibiotic I use) to be back to my new "normal". Probiotics MESS me up big time. And my stool never smells but on probiotics I swear my whole house smelled like a sewer line exploded.
