I have a cold right now, and of all the symptoms, have a runny nose. I'm taking junior strength tylenol (I can't swallow pills... don't know why...) and it randomly occured to me, we all know coke/pepsi is notorious for "eating away" things, so would drinking coke/pepsi/etc... actually make this medicine (and others I guess) less effective...
stupid question yes, but I'm running on soooo little sleep that it's intriguing me quite a bit
[edit]: what makes expired cough medicine taste so much worse?
