Maybe tea would suit you better? It contains the L-Theanine others here have recommended, and usually has less caffeine.
You could also just make smaller servings if you want to drink coffee twice, literally just use a smaller cup, or don’t fill it all the way?
Aeropress might be good too - it makes a nice strong tasting cup of coffee but the water is not in contact with the coffee for as long as it is for drip coffee.
Sometimes, when I have my second cup of coffee, my chest gets tight, but I don’t always have that.
