Honey,
you may recall it was me to say: "how about orchie?".
In your present situation it seems a good thing to do. As it needs to be considered case by case and in your case it make sense to me.
Though, you mentioned you where on lowest dose Spiro, = 1 tab/day and we know that is the lowest that works --- if it works.
There are folks that take 3 to 4 tabs a day (some 6!), now your liver may start complaining and it's no more banans, figs, plums, potatoes, and on and on... you know then: Potassium sparing...
So, if 2 max. 3 tabs a day don't cut it, orchie it is, if it was me.
I hope this makes sense.
Axelle
