Could you check my sentence?

There are two daily habits I focus on. The first is reducing my coffee consumption. I used to drink 2–3 cups of Americano a day, but I realized I was consuming too much caffeine. So, I set a goal to drink coffee only twice a week. The second habit is taking my supplements. I take them every morning, afternoon, and evening. I've noticed a clear difference since I started taking them regularly.

“I used to drink 2-3 americanos a day, but I realized I was drinking too much caffeine” We don’t say “cups” in this context, can’t explain why, but we would say “cups of coffee” “I’ve noticed a clear difference and started taking them regularly” “Realized” works, but sounds a little unnatural to me. Then adding the additional “I” pronoun sounds non-native, if you’ve already established the subject, no need to add it again. Removing it sounds much more natural. Good work!

You wrote a paragraph, not a sentence. Several things need to be changed. First, the prompt asked you a personal question, so the beginning of your answer should use 1st person framing, not general framing ("there are"). Second, "used to" should be followed by a verb in infinitive/default, not present progressive. And third, outside of continental Europe and maybe Australia, people might not be familiar with the coffee drink called "Americano", so you could potentially replace that word with "coffee". Last, even though native English speakers take a shortcut and call nutritional supplements just "supplements", as a non native speaker it would be better practice to use the full descriptive phrase "nutritional supplement". If you do that, there can be no doubt what thing you are talking about.  Same advice for any other "shortcut" words that native speakers use, like tie or glass. If you mean eyeglasses say eyeglasses and if you mean necktie say necktie (or twist-tie if you mean twist-tie, etc). That will actually make you sound more competent than copying how natives speak.

Two habits are equally important to me. Firstly, I try to drink less coffee. I used to drink 2-3 cups of Americano each day, but I noticed I was having too much caffeine, so I set a goal to drink coffee only twice a week. Secondly, I take my supplements. I take them every morning, afternoon, and evening. I’ve noticed a clear difference since I started taking them regularly.

>There are two daily habits. No, there are millions. You mean, "I have two daily habits." >The first is reducing my coffee drinks. That is not a habit. Drinking coffee every day is a habit. >I used to drinking I used to drink. Past tense.
