Hello, For anyone using guaifenesin, look for it at you local DOLLAR STORE. I found 15 Tablets for just $2.00. I purchased thier product "Mucus Relief Expectorant" in a blue & white Box. Also, if you use nasal spray (alot of us fibro's have nasal problems) the generic nasal spray works better for me than the expensive name brands. The brand I purchased is in a red & white box, and named "Nasal". It is also a good idea to get your generic asprins & ibuprofin for $1.00 as well. I am in Philadelphia Pennsylvania, and Dollar Tree is the major chain here. I am a Realtor, and I have to keep active, and buying these things at a discount helps. I hope this helps!
