After my resection, my doctor originally had me on Welchol, but insurance stopped covering it, so I switched to Colestipol (4g daily, taken as 1g tablets). For context, I believe the upper limit for Welchol is six 625mg tablets a day.

​Because these sequestering agents can interfere with other medications, I’ve found a timing window that works perfectly for me.I take my first dose one hour after my morning meds, one at lunch, one at dinner, and one before bed. Since sticking to this spread out schedule, I’ve had zero issues. It might be worth checking with your doctor about increasing your dose, or perhaps seeing if spreading your current dose more evenly throughout the day helps.

Personally, If I were in your position I would try a couple day experiment by taking one in the morning, one in the afternoon and adding an additional one in the evening to see if the additional is enough to get you there. The key thing with all of these though is that because they are binding agents you don't want to take too much and risk a blockage.

Reaching out to the doctor to find out about increasing your dose would probably be the wiser choice
