Yeah, that lines up with what happened for me. Roughly seven months into using tirz, those stomach troubles have faded away for the most part. Yet enzymes to help with digestion made a huge difference early in the process. Taking magnesium oxide each day also turned out to be really useful.
Taking digestive enzymes has really cut down on the side effects from my medication. When I stopped for a couple days the issues came back stronger, but restarting them made them go away again. Pick a quality one and take it right after breakfast, never on an empty stomach.
