Brain fog / memory problems

Hi! I was in a deep addiction and taking up to 300mg per day until I stopped cold turkey in April. The biggest issue I’ve had since stopping is horrible short term memory, and I am getting concerned at this point.

Examples - I’ll go to text a friend or look something up on the internet and will forget what I wanted to say/type almost immediately before I can write it down. I’ll also forget what was being talked about mid conversation with a friend, or I’ll forget what my therapist originally asked me after I talk for a little bit. I’m constantly needing to ask what we were talking about. Thankfully, those I love are understanding.

Is this something my brain can heal from? Anyone else have experience with this?
