Thank you for your answers.
From the first post the wrong thing that applies to me is that I always drink water before and after meal. Some time ago I used not to, but since I got constipated a few times I started drinking with meals so the stools don't get hard. Another thing is that I feel like food is digested faster with water, at least it seems that it stays shorter in my stomach. But could drinking with meals cause lack of urges? Or could I be drinking too much water at all? I usually drink at least 2 litres per day (it's about 10 glasses) of plain water + a few cups of tea. So my stools are very soft, but maybe that could be the reason of no urges?
I've noticed that grapes have good effect too, at least BMs are really good, but still no urge...
By the way I'm vegetarian too
Though I eat dairy products, mainly yogurt.
As far as Metamucil goes I've read a lot about it, but they don't sell it here so I can't try it (I couldn't even find something else that contains psyllium). But in their website they say that one dose has 3 grams of fibre and I wonder if that would help as I definitely get 20-30 grams of fibre in my diet, maybe even more, all my meals contain fibre!
Today I tried not to drink with my meal and will try it for a few days, maybe that would help..
