Guaifenesin / pseudoephedrine
cough and nasal congestion
"The medicine itself works to relieve chest/nasal congestion but it keeps me from sleeping...first night I was thinking maybe it was because I was traveling but 2nd night same thing, and it's almost like it automatically wake you at around 2am. My second dose yesterday had me jittery and groggy during the day...don't know if I will continue to take this or not. I need sleep!"
