Так-то used to - это то, что ты раньше делал, а сейчас, в силу каких-либо обстоятельств не делаешь.
I used to go to the childrengarden when I was a child.
I used to wake up at 12 o'clock in summer
I used to watch cartoons when I was a child
I used to play with toys when I was a child
I used to take a medication when I was ill
I used to go to bed early when I was a child
I used to come home early when I was smaller than now
