Hi Av23,
That sounds familiar. The 3-4 week mark has been my downfall the last 3 times, and I think its because I have started to relax, returning to my old ways, too quickly.
I am down to one Movicol sachet a day (taken at night). I've replaced my morning sachet with a mug of hot water with lemon and a small glass prune juice.
I'm about 10 days on from my last tear, so I have a way to go yet before I can say I am recovered. In fact I'm not sure I will ever say I am fully recovered. It feels a bit like being an alcoholic, you're always 'recovering'?
I'm enjoying feeling well and pain-free, I don't take it for granted and I thank my lucky stars each day I continue to feel pain-free and blood free down there. I should have done this years ago. I'm losing a bit of weight which is welcome too as I am eating so much healthier than before.
So I'm staying off the crisps, nuts, red meat, white carbs and big sessions on the booze for a little while longer yet. My next project is to see if I can get down to 1/2 Movicol sachet a day, and if I can, I'm going to stay on that for a month, see if I can get into the so far unknown territory of 6+ weeks of being pain-free.
Good luck to you too, it sounds like you do have the ability to recover but also have the ability to self implode, just like me, so keep strong ;-)
