The normal bacterial population in your large bowel was severely disrupted and simply doesn't recover quickly or readily. Since you seem to be slowly improving and at least not getting worse, patience is your best option. There are many probiotic formulations and you may experiment to see which might work better for you, including dietary ones like live culture yogurt and kefir.
