Decaf after your cutoff
Short answer: for most people, no. A cup of decaf usually has about 2 mg of caffeine, compared with about 95 mg in regular brewed coffee. That's why decaf is the go-to drink after your cutoff.
If you're very sensitive, several cups of decaf in the evening can add up. In that case, herbal tea is the fully caffeine-free option.
