Homemade Iced Coffee Fail

I have a problem.... I love coffee.  I mean, really love coffee.  I enjoy my coffee at home each morning and then bring a travel mug full of coffee goodness with me to work.  By lunchtime, I am craving my next fix.  We have a local coffee shop but they constantly have new employees that probably don't even drink coffee.  I can't imagine... but anyway, they either ring up my order wrong or the espresso has a bitter taste.  So I often get frustrated at the lack of proper coffee shops in my town and look for alternatives.  This morning I tried something new after browsing Pioneer Woman's recipe for iced coffee.  No I didn't follow her recipe.  I tried my own... drum roll.... it's awful.  Actually has a hint of old coffee pot or ashtray somewhere in it.  I made an extra large pot of my normal coffee, enjoyed it with breakfast, prepared travel mug for work, and poured the remainder in a Nalgene bottle.  I topped it with lots of skim milk and vanilla syrup.  So exciting!  Now it's after lunch and I pour my coffee goodness over some ice in my favorite Starbucks plastic tumbler cup.  Hoping that will make it taste like Starbucks iced coffee.  One sip... eh.  Two sips... uh oh.  Three sips... what is that twang? Four sips... ok this is not good.  I accept defeat but I will drink it because that's what a junkie would do.
