Stacking: caffeine + nicotine
If you also use nicotine pouches, the two stimulants stack — both raise heart rate and both suppress appetite, and the combination on an empty stomach is the single most common "wired but fried" pattern SteadyBeast users log. A 80mg can plus a few 6mg pouches before lunch is a bigger nervous-system event than either alone. See the nicotine pouch database for the other half of your math.
Good to know: Red Bull keeps a constant caffeine concentration (~9.5mg per fl oz) — bigger can, proportionally more caffeine.
