How can I stop being a compulsive liar?

Every time you lie, journal about it. You will soon find that you are doing it mostly for comfort in yourself, or for a silly and preventable reason. If you don't know the reason yet, start journalling. It is eye opening.. Write in pen too.

Admit to someone you trust your problem. Then you can practice not lying to them. When you do lie to them, immediately tell them you've lied. If they really care about you they will understand and want to help you.

If you lie often, you should consider things will be worse when the truth is finally discovered. That doesn't feel good.

It can help to keep a journal of the lies you've told, and the consequences that came out of it - seeing these will be a reminder of why it is ultimately better (even if harder) to tell the truth.

Realizing that lying separates us from self and others and leads to negative distrustful relationships.

It's natural that you have an ingrained tendency to lie ..maybe because you're a very personal person who doesn't like sharing much about yourself with others? It's okay to accept that and start making an active habit to catch yourself when you feel somebody is being intrusive and you feel you're about to tell a lie . Then tell the truth or just tell them you'd prefer not to share

Accept the reality of how things truly are. Accept people's choices and decisions for what they are instead of feeling the need to lie for your own reasons.

Think before lying, know what lying actually is, and stop it one step at a time rather than stopping it all together because that would be tricky. Tell yourself every hour how bad lying can be and what it can get you into (for example splitting up from serious relationships).

You should tell someone. Trust me, I used to be a compulsive liar, I actually enjoyed it, but later on I understood that what I was doing was unfair to the ones I loved. So, in my opinion, you should tell someone you really trust to point out to everybody when they feel like you are lying, so you'll have to be honest, if you don't want to lose the persons you love. I understand it may be drastic, but that's probably what you need

try to think if these lies will hurt those around you, and how it will make them feel. think like Phinocho, when he lied his nose grew, so every time you want to lie, just think oh no my nose will grow.
