At my therapy session today my therapist and I talked a bit about some intrusive thoughts I have. Mainly the intrusive thoughts I have about faking/lying/exaggerating things I say or do. I fear that I'm lying and making things up and then I tend to go through memories, conversations and past events repeatedly to make sure that I've told no lies. My therapist says that's OCD.

He told me to say "I'm lying" or "I'm a liar" every time those thoughts enter my mind and to stop there and not try to prove to myself that I'm not a liar. He said he wanted me to tell myself that I'm a liar over and over and over again without thinking things like "no I'm not" etc. He said to do so until the thoughts lose their meaning or something.

I'm going to try it but it sounds a bit weird to me. Has your therapist suggested similar things to you? Is this the equivalent to people with for example intrusive thoughts about contamination (which I guess is a more "visible" symptom) not washing their hands when they feel like they're not clean? I've heard something about ERP. Is this it? Has it worked for you?
