Thanks everyone, I just put in an order for VSL#3. It won't be here until the end of the week, but at least the antibiotics will be clear by then. I'll definitely make sure I eat some prebiotics as well. I have a bad history with SIBO's and tend to get them easily (altered gut due to a gastric bypass 8 years ago) so I'm definitely taking care, especially because the symptoms cropped up so quickly this time. Thanks again!
