cough and nasal congestion
"Whenever I use the 12-hour tabs, it helps almost immediately in satiating my urge to cough and/or does a good job of loosening whatever junk is in my chest. Grateful for that. However, it is now 1:46am -- been eyes-wide awake since 12midnight. I took 1 pill around 3pm, fell asleep nicely by 9pm, but BOOM - now jittery and think I'm going crazy, wondering why I can't fall back asleep. Praying. I will not take this anymore, or will only try to take an a.m. dose & skip the p.m. dose. Glad the mucus is lessening, but so not glad about missing sleep."
