Does Turkish coffee have more caffeine?

Not really. Turkish coffee is more concentrated. Compared to regular drip-filtered coffee, the caffeine dose in Turkish coffee is one third that of espresso, two thirds that of filter or chemex brewed beans, and half that of decaf filtered beans. Caffeine levels are not altered by boiling for long periods prior to being drank because it does not chemically alter caffeine. The more cream you use (if any), the higher your sugar intake will be (which might make you feel worse). It's also worth noting here that adding sugar actually reduces its antioxidant value rather than increasing it."
