Have recently started a course of Symprove. I have a three-month supply. I'm on day 6 and I have felt very washed out this week - the fatigue has been quite brutal and has been present throughout most days. I need to stick with it because I have no firm evidence that I'm not just going through a 'crashy' period, and because I've paid decent money for the three-month supply. Anyone like to share their experience of a course of probiotics, particularly stuff like Symprove?
