My morning pills I can take all at once, but my evening pills I usually take in two to three handfuls. It depends on if they give me one dose of pills as three 100s, or as 2 150. the 2 150 are harder to swallow and will get stuck with all the others going down. Then I take my megavitamin by itself. It's big enough. Then. I'm overfull. lol!!
(also i remember something about most tablet vitamins not dissolving well and being largely wasted, but this is from years ago, so idk how true it still is or hope much better gummy ones are)
