Chest cold, cough, no energy, wheezing. taking regular robitussin (guaifenesin) and drinking lots of water?

Chest cough: You may have bronchitis or pneumonia so see your doctor for a possible chest xray and modification of your medication. You might do better with albuterol for your cough and possibly an antibiotic

See below: Not sure what your question is, but with your mentioned history of wheezing and tobacco use, I would recommend you see a physician. As a general rule, most OTC cough medications (Robitussin) provide little releif, especially if you are wheezing.
