Ive been on spiro for almost two years. I've noticed that I get have a dry throat/mouth but usually only notice it at night . I only take Spiro so I don't know what else could be causing it but now I'm starting to wonder.
It's most definitely a side effect, and I get it bad at night too. Normally I'd just deal with these things, but I'm a musician and its really affecting my singing voice. :(
