Victoria, instead of breaking them, try a pill cutter or a very sharp knife. I've cut small pills before with a sharp paring knife, usually works well if you do it quickly, just like pop the knife through it.
And, like greyhound said, if they do crumble... just use them under your tongue. Same medicine, no matter how it makes it to your system..lol. If the other half crumbles, try putting it in a plastic baggie instead of back in the bottle.. in the bottle it will get mushed up by other pills and end up a powder.
I'm not procrastinating----I'm still doing yesterday!!!!
I have no medical training, any medical opinions expressed in my posts are just that....opinions.
