Mark, we're truly sorry to hear about this, and we hope you're feeling better. While we have safety checks in place, it is normal to notice small changes in your body such as gas or bloating. If this is what is making you feel sick, please know that these changes are a result of your body adjusting to Align, and you should continue to take it to get the best results. If you are concerned about how your body is responding to Align, please check with your doctor. We'd like to collect some additional details about your experience and make a detailed report to our team and help. Please call us at (800) 208-0112.
