I agree with your thoughts, 3/day seems like alot to me. I was told by my GI to only take 1 when I absolutely have to (special occasion/travel). I have taken 1 on a few occasions and it worked. I can imagine what would happen if I took 3/day for a few days. We are all different, maybe your situation requires that. I would check further into it, get a second opinion from another DR. Maybe someone with more immodium experience will come along. I wish you the best with it.
