Sensitive skin-- the adhesive on the patch made my skin burn, not the nicotine section of the patch.
Other adhesives also burn my [pain in the neck, stupid, sensitive] skin .
Don't spend too much money on it to start, in case it burns your skin, too.

Too much nicotine can kill. Read the package directions so you don't over dose. Nicotine with caffeine can cause headaches, too high blood pressure, stomach upset.
Go carefully. Use common sense. Observe your own body's reactions, not what somebody else says should be okay. You might be extra sensitive.

Good luck!
