Mucinex D
"Would not recommend. A 20 year old college student who desperately needs sleep but hasn't because the label on the box forgot to highlight and bold "You won't be able to sleep!!" Took two pills at 10:30am and about an hour later I was very jittery, paranoid, anxious and my heart rate was going insane. It's now 10 pm and my eyes are still dilated and I still feel weird. Would not recommend the whole dosage, or just stay clear in general."
