I was given anti-gallstone capsules in hospital, which I have to take for 6 months. They're huge and they're also hard capsules, not the softer variety.
I take 4 per day, 2 in the morning, 2 at night. I space them about 5-10 minutes apart and take with plenty of water. The first time I took two together, I guess they got stuck until they dissolved and it caused me a degree of pain.
Plenty of water and spacing them out and you'll be fine.
