Re:Now inhale caffeine; soon inhale food!
Nutrisystems had flavor sprays several years ago.
They discontinued them.
As for caffeine, this would be wonderful for those that suffer migraines. I keep the little 2 ounce pure caffeine add to coffee cups next to my bed because every migraine I've ever had occur at 3 - 4 AM in the morning. Gulp one down when I realize that the headache is a migraine and it doesn't progress.
They also go with me when I travel! I haven't had a full blown migraine since I implemented this "cure" two years ago.
Caffeine is dangerous, though. The FDA might need to chime in on this one as it's administered more like a drug than food.
