Benylin E (for expectorant) also has 200mg per tablespoon of guaifenesin, Buckleys has an expectorant for cough that is 100mg per tablespoon, and I have heard mucinex is good but I have not seen it. Good luck.
my cousin's wife did it and she got pregnant, but she may have ended up pregnant without it too. give it a try.
Has it worked for anyone?
Robitussin is a brand name of a product that is based on guaifenesin, an expectorant. There are other guaifenesin based cough syrups also (Equate also has one). It is used in TTC to thin the CM mucus to make it more sperm-friendly. 1-2 tsp. twice daily until ovulation. Make sure the product only contains guaifenesin without added decongestants or antihistamines, which could dry your CM.
BEWARE:Dextromethorphan, an ingredient in some cough medicines, may cause birth defects.
