It is reassuring that your symptoms are improving. To safely resolve the remaining loose motions, you can take a probiotic supplement containing Saccharomyces boulardii or Lactobacillus to restore your gut flora after antibiotic use. Avoid anti-diarrheal medicines like loperamide unless specifically prescribed by your doctor.

Stick to a bland diet like rice and yoghurt, and consult your treating physician to ensure your blood sugar remains stable and to check if your diabetes medications need temporary adjustment.
