No urgency to go. Been almost a year. :(

I have tried every laxative out there and every medication under the sun. So far what works for me is Linzess, but it is so so expensive even with a savings card. This month it was 350$ and I can’t afford that every month so I’m back to taking miralax and dulcolax once a week to go…. I take 3 of the 5mg. If I don’t take any laxatives I have no urgency to go and haven’t had any for nearly a year. I’m 25F, healthy, hydrated and eat a well balanced diet. I don’t know what’s wrong with me and this constipation is really taking over my life :(
