My throat is shrinking

As a teenager I could easily swallow the usual kinds of pills. I don't know what changed but now the disk-shaped pills are liable to get stuck in my throat on the way down: I much prefer the lozenge-shaped ones that have only one large dimension instead of two though it would be nice if it were easier to tell in advance before buying. Perhaps chopping a pill in half does not greatly change its dissolution rate: its absorption profile may be similar if the length of the smallest dimension remains unchanged. Let's hope so.
