There are plenty of drugs out there that will make you think you have become more intelligent but I'm not convinced they actually work. I think that they are actually counterproductive in the long run.
Coffee is a stimulant and as such has no effect on intelligence by definition. It does increase energy and alertness, but neither of those have anything to do with underlying intelligence. Brain fog has to do with energy and alertness also and not underlying intelligence. There are a number of things which may help with brain fog including a well-balanced diet. There are also various stimulants, so-called nootropics, and a number of herbal substances which may do any number of things behind the scenes. Often people with vitamin deficiencies (for instance, B-12) show cognitive impairment and simply reversing the deficiency can return the person to their normal level of intelligence. Nothing I've seen shows that you can actually boost someone's intelligence above what is normal for that person. But, again, that has nothing to do with brain fog which is simply a matter of alertness and energy and which may reflect some kind of temporary neurotransmitter shortage or surplus.
