Capitalize "i" into "I". Add commas to avoid run on sentences. It is also spelled "Caffeine". I am also not sure what you are trying to say but I assume you are talking about someone

fFor me i, I like coffee but only in the morning , be cause I'd come back tofrom the gym and because he havof the caffen and the caffen dont me sleep in theine I can't sleep at night. For me, I like coffee but only in the morning, because I'd come back from the gym and because of the caffeine I can't sleep at night.

I took my best guess at what you meant to say. Perhaps it'd help if you provided the native text. (1) The pronoun "I" is always capitalised. (2) Do use commas freely as they can make a sentence much easier to read.
