Remind can be used with two prepositions “of“ and “about“ but each is used for different situations.
“of“ used of memories, connotations
His voice reminds me of my brother's.
Her eyes reminded him of past memories.
And about is used when we're talking about a future event.
“She reminded me about our holiday.”
But if there is a sentence coming after remind we don't use about
“She reminded me when the meeting starts.”
Hope that helps
I don't get used to is rare but isnt grammatically incorrect. If we're talking about a situation we're not used to “I'm not used to...” is the most accurate form. But I don't get used to can be used for general descriptions like
“I don't easily get used to new cities.” though “can't” be used in this situation as well.
