Thank you Christine! You are right - he is miserable. Said this morning that this has to stop. Thoughts about interactions from mucinex or robitussin with all other drugs he remains on? Probably should consult with doctor to be safe, eh? Our doctor is excellent about responding to emails. I'll kick one off now, but again, now I have some background that it is not uncommon and that an OTC med may help alleviate some of the coughing. Thank you thank you! Have a great Saturday! It is beautiful here and would love to get him out for a walk! Take care! Big Hugs!
