You can count to:

162

Because:

It's quite obvious that the 1 will be the most used digit, since it's the lowest non-zero digit. Now, there are twelve 1 from 1-20. After that, it's an additional one 1 per ten, up til 99, making it 20. Now, we continue adding 1 every count, in addition to the extra ones in 101, 121, 131, 141, 151, 161, a and 110-119.

Here's an exhaustive demonstration:
