Is there a difference between caffeine in Coffee and caffeine in Coke?

Caffeine is caffeine. Its all the same stuff.

yeah coffee has about double the amount of caffeine as coke. most pops with caffeine have 35-50mg (pending on brand) per can and coffees have  ~100mg per cup. but like the first guy said caffeine is caffeine, there is just a lot more of it in coffee.

the "long" heart beat is probablya PVC palpitation, i get them too if i have a lot of caffeine. theyre harmless but annoying. feels like your heart beat really fast twice then pauses for a second, then the next beat is really hard im guessing? youre probably kinda sensitive to caffeine like me, limit yourself on caffeine or buy some caffeine free coke/decaf coffee

there's a lot more caffeine in coffee than in a coke. you probably feel antsy because you're consuming a lot more caffeine than your body is used too.

 Just to inform you, coke has other bad chemicals in it as well, such as phosphoric acid (deteriorates bones!), and tons of sugar, just so you don't get confused thinking that coke is more healthy than coffee.

I'm not sure why it would affect you with coffee but not with soda, hmmm.  The sugar and caffeine would be worse!  Not much you can do to neutralize caffeine, someone would be rich if they'd invent it!  Drink alot of water is the best I can do, mainly to re-hydrate as coffee makes you dehydrated.  So does soda by the way, and with the sugar it's double whammy.  Ever noticed you want more after drinking a soda?

the caffeine in coke and coffee is the same ol caffeine the only difference is the amount that's put into each one.

Caffine is stronger in coffee than in coke. to counter act the panic attack you need to drink milk i per fer 2% milk.

There are many other compounds in Coke and coffee that may cause this reaction.

Coke is carbonated (carbonic acid) and 'fizzes' as a result. Carbonate is really good to soothe an upset stomach. Alka-Seltzer is basically calcium carbonate (the calcium keeps the carbonate shelf-stable until added to water) and the 'fizz' is the same 'fizz' found in your soda. The principle is the same, though - soothe your upset stomach.

Coffee, on the other hand, has 'phytates'. These are big carbon molecules that bind enzymes and proteins in your stomach. Your stomach has a mucus lining (to prevent it from digesting itself when it secretes hydrochloric acid). However, phytates react with this mucus lining and alter its physical properties. Rather than being like mucus (slimy), it becomes slightly harder and less watery.

Granted this only happens on a small scale, but regardless, it is best not to drink coffee on an empty stomach. Hope this helps!

no hun no difference caffeine is caffeine the only difference is the amount per cup. if you suffer panic attacks you really should consult your doctor you may be allergic to to the actual coffee bean itself or perhaps one of the other chemicals used in the coffee. dose this happen when you drink instant powder type coffee or freshly ground coffee? or try decaff, but see your doctor sor sure i know a man who ended up in hospital from a cup of coffee.

I echo the first answer caffeine is caffeine. If you are looking for something to neutralize the caffeine, the simplest solution would be to not ingest it in the first place.
