Red Bull, Rockstar, Monster and similar energy drinks have ~32mg/100ml (I've seen anything from 28 to 32, but 32 seems to be a legal limit and the most popular).
A 500ml can of Rockstar or Monster has 160mg of caffeine.
The caffeine content of regular caffeine pills I can buy at the pharmacy (plain packaging, just branded as "caffeine") is 0.2g per pill, i.e. 200mg (or 100mg per half).
A cup of regular coffee typically contains about 95mg of caffeine.
If a handful of servings of 100mg of caffeine per day would pose a major health risk, the majority of the population in developed nations would already be affected, whether they drink Club Mate or not.
For reference: I would say that in a given day I don't think I've ever drunk more than two liters of Club Mate. Normally I drink about two bottles over the period of a work day. I barely ever drink it outside of work.
I would say that on a typical day (including holidays and weekends) I consume between 100mg and 250mg of caffeine. That's the equivalent of one to two-and-a-half cups of coffee.
EDIT: Google seems to agree that up to 400mg of caffeine a day is safe for most healthy adults. I should probably also point out that some people are just naturally very sensitive to caffeine, so that may explain why you reacted so strongly to Jolt Cola -- especially if you do not normally consume any other sources of caffeine like coffee, tea or dark chocolate.
