@PaulL I’m pretty sure your salt fix worked. I can’t be 100% sure because it had been 8 days since my last BM and that’s around the time I actually move naturally. But it felt different, more like I’d taken a laxative, so I think it was the salt. I think I probably took too much as I hit the effect that you described.
That’s another reason I think it was the salt as that never happens to me unless I’m ill. That resulted from about 1.5 teaspoons of extra (not on food) salt which is about a full teaspoon more than my regular consumption. I’ll try again at a slightly lower amount.
If this is it I’ll be so excited. I’ve struggled with this problem for two years now. I’ve read your solution many times before but was just too scared of that much salt.
Big thanks.
