Hi Paige,
I usually get the tablet(s) and crunch them slightly between my front teeth to break them into around four plus pieces each then I place them up in my top lip either side of that strip bit. It stays there. You can eat, talk drink and they don't get affected just dissolve away.
I usually take before I go to bed and dissolves overnight.
That was hard not to nominate they ,how many ,but I think I passed not mentioning dosages,please edit if needed.
