While I was in the US I got some Mucinex, since you can't buy it in Canada (that I've seen).
When do I start using it? What's the dosage? I got a mega pack (I think 50 pills) of the lowest dosage.
I'm thinking it would be the same as taking EPO (Evening Primrose Oil). I take the EPO from the start of AF until the day of "O" and then I stop. Mucinex will help with an increase of CM, so you want an increase before "O".
I've bought Mucinex here and in the US.
