I don't know how big they are but I genetically have a smaller esophagus (got it from my dad and all my siblings share this trait) so I can't swallow nyquil/dayquil pills but anything smaller is fine. I put them in my mouth, then take a big gulp of water into my mouth so the pills are floating in the water and I can't feel them, then I swallow and continue to drink/swallow more water after to make my esophagus do the motions to get it down. Works great for me for most medication.
Also if I'm crushing pills I've noticed I can do it with my teeth and get them submerged in water like above and with a quick swallow I can barely taste them.
