I used a liquid glycerin suppository last night with almost zero result (2 small, hard stool expulsions) Can I repeat and when should stool be normal?

Let's define problem. Doctors define constipation as stools less frequently than once every 3-4 days. Patients feel they are "constipated" when passing hard or small volume stool, or they feel full & bloated. Been x-rayed to check you're not blocked? We don't know if your gut is sluggish or your rectum works correctly--these can be tested for (sitz marker study & anal manometry, respectively). See a GI specialist.
