Mucodyne is good stuff . I take 30mm everyday . For me it works best before exercise I take 15mm last job before I swim guaranteed to clear the chest . Swimming is great for breathing stroke and breath combine increasing the affect.

My problem is getting in to the bottle that child proof cap we put the old cap on new bottle so it's easy to get off .

Second dose it took one hour before bed . If it's too close to bed time I get problems swollowing the increased saliva . I know we are all different so you have to try which times are best for you.

Mucodyne releases Mucus so over night I tend to get more deposits in nasal passageway which leaves me needing nebuliser every morning
