Native English speakers, could you please help me with these issues?

1. Is this sentence correct:

"Caffeine increases the CAPACITY OF ALERT."

2. Consider the following sentence:

"Many people experience a DIP in energy several hours after drinking coffee."

a) Does 'dip' mean 'decrease'?

b) By the way, would it be correct to say: "Many people experience a RISE in shortly after drinking coffee

    1. no, this sentence is not correct. something along these lines would be better: “caffeine increases alertness”

    2a. ‘dip’ usually means a low but is followed by a high, like a dip in a road

    2b. a more correct way to say this would be something like: “many people experience a rise in their mood and energy after drinking coffee”

    1 no that's not English

    2a no, a dip is a low point, usually from the end of a decrease to the start of an increase

    1. No that sentence is not correct. Do you mean "Caffeine increases alertness."? Alertness is the state of being alert.

    2. Yes, 'dip' means a reduction or decrease in that context.

    3. The sentence is incomplete. There is a word missing after 'in'. I think the missing word should be 'alertness' or 'mental stimulation' or something with a similar meaning. Apart from the missing word or words, yes, the sentence would be correct.
