    Guaifenex cough, insomnia

    I like this medication so much I gave my daughter and her boyfriend some for their congestion and ear aches. Now they tell me they want to be alone more. I am not sure if the medicine increased their libido or not.

    Incredible dry mouth. Since taking the pill 2 days ago, I've only been able to sleep for 3 hours. I can't fall back asleep but I'm still tired. Sleeplessness triggered a manic episode a long time ago. Be careful.
