I had trouble breathing, my throat burned, my eyes watered and I was constantly coughing. Finally I realized that I had just started my job in a backward workplace that still allowed smoking about two weeks after I began using Welchol. I worked with our city council to get smoking banned in all workplaces and then finally did. All of my problems are gone, now that I can work in a smoke-free environment and the few problem addicts can't smoke on the premises. The Welchol was never the problem, it was toxic tobacco smoke.
