Anyone taking Linzess?

Hi, new here, but not new to Healingwell, as I have ulcerative colitis, but in remission. My question is I have been experiencing terrible stomach pains with gas and bloating almost everynight and doctor did an xray on my stomach and said I had mild constipation, but it sure doesn't seem mild, the pains sometimes at night are unbearable until I go to the bathroom. I have been on senna and miralax daily and it seemed to help, but it keeps coming back I just started renew life cleansemore the last two days and it helps in the morning, but I still get stomach pains at night. I was thinking about asking doctor for a prescription of Linzess but wanted to see other peoples experience. Thank you.
