Hi Grace. I haven't had issue with pills, but with alcohol. I just wanted to give you a warm welcome to SR and to tell you that you have come to the right place for support. Have you been to a doctor yet? I would advice seeing a doctor about this. Your stomach issues should be addressed.
You will not fail if you keep going any lengths to remain pill free. You certainly can do this and kudos to you for having a supportive mother in law.
