AP-
Usually within 30 minutes after taking VSL, I have to go to bathroom and, usually only a little bit would come out. For hours I would feel I have to go but don't feel emptied. Also, first several day of starting VSL, I had excess gas and high frequency, which improved over time.
With Align, I don't have those issues. I don't have to time it because I can take and leave home immediately. Whereas, with VSL, I usually don't leave home for an hour or so. Align has no impact on my frequency.
Hope this helps.
Thanks!
