Race conditions in Laravel when using split "read" and "write" database connections

I have a Laravel application which uses a lot of AJAX POST and GET requests (Single Page Application). Once an item is saved via POST, a GET request is sent to reload parts of the page and get any new data.

After enabling split read and write database connections using the Laravel connection configuration, the application runs incredibly quickly (never thought this would be a problem!). It saves and then requests so quickly that the RO database (reporting just 22ms behind) doesn't get chance to update and I end up with old information.

I have enabled the sticky parameter in the database configuration which I thought would mitigate the problem, but the POST and GET requests are separate so the stickiness gets lost.

I could rewrite a large portion of the application POST requests respond with the correct data, but this doesn't work for reloading many components at once and is an enormous job so I see this as a last resort.

Another idea I had was to modify the getReadPdo(){...} method and $recordsModified value inside the Database Connection class so that the stickiness is saved on the user's session for up-to 1 second. I was unsure if this would cause any further issues with speed or excessive session loading that it would cause more problems.

Has anyone experienced this before or have any ideas on how to tackle the problem?

Thanks in advance.
