Hello, have been reading a number of topics on here regarding constipation. I have been on LT for 4 weeks now, and it has steadily been getting worse and worse, every 4 days or so when I eventually go. Today I think if I don't take something, I'll pass out I am going to go round to Boots shortly and pick something up, just wanted to check on here if I can get any laxative, or will certain brands knock me out of ketosis? And which one would people recommend/fast acting etc? Thanks.
