What is the negative form of "I used to be"? I often hear "I didn't used to be" but that sounds awfully wrong in my ears. What's the negation of "I used to be"?

Understanding the Context

Surely not "I didn't used to be"? I am trying to find out if this question is correct. Did Wang Bo used to be awkward? Should I write "use to be" instead of "used to be," or is "used to be" correct in this sentence?

Key Insights

When is "some" used as plural and when is it used as singular? Here is a question that has been nagging me for a few years: Which is the right usage: "Didn't used to" or "didn't use to?" Examples: We lived on the coast for years but we didn't use to go to the differences - Didn't used to or didn't use to? - English Language ... If "used to" is a set idiomatic phrase (i.e. not a tense), then why would it change its form from "use to" to "used to" for the sentence as it does in the positive?

Final Thoughts

In the sentence given though, help is quite definitely a verb, and used in an affirmative context, so it would be best to have either a plain infinitival or to -infinitival following it.
