@ahs389 agree with all the tips Sue provided. Definitely make sure you are taking a good quality probiotic. Do make sure to space out the antibiotics from the probiotics, ie take them about 2 hours apart. I was also told I could take my meds with or without food and found having something in my stomach helped so would plan on a small snack if not taken at mealtime. I also used sea bands or similar wrist bands to help with any nausea along with ginger.
