I am a 38 year old mum with one toddler, so can absolutely relate. I take amitriptyline at a very low dose for nerve pain from MS, but like Lyrica, it is sedating and I can't up the dose at all if I am to function the next day.
I agree with HappyPoet. Get a referral to a gastroenterologist asap. I used to have severe constipation and then occasional diarrhoea. TMI alert but once I didn't 'go' for over 10 days. I eventually was tested for coeliac disease and I thought, no way could I be coeliac, but I am. It resolved the severe constipation a lot. I have to watch it though because like you, without keeping an effort going every day, I get severly constipated. I have to use a combination of:
*high dose acidophilous tablets each day
*lots of water during the day, but ending at 6pm because I have bladder issues too!
* I drink strong coffee in the morning to counteract the sedating effect of amitriptyline, and it also seems to help me to 'go'
If I leave one of these things out I immediately have a problem again. Of course I follow a gluten free diet all the time too and definitely that helps.
I hope you find some solution for you, really feel for your situation.
