I get a little frustrated when people say that using techniques only entrenches and enforces a stammer. If this were true there wouldn't be thousands of stammerers who happy say that they control their stammer to a point where it can be almost invisible and more importantly the fear of speaking, and therefore the fear of doing every day stuff evaporates. My go-to support comes from [Empowering Voices](https://www.empoweringvoices.co.uk/), there are a few videos on here which demonstrate the technique and describe how it works. It's also a charity, so it's great to not have to support an organisation that financially benefits from the misery of stammering.
