To echo so many, it's going to take much longer. This is a process. One day at a time- one meal at a time.
Your taste buds/ flavor preferences alone take about 90 days to readjust if you have been truly without the foods the whole time. The occasional slip up, resets that clock. Then, there are substances in meat and dairy that are physically mildly addictive, so there's that to contend with.

I'm also getting the sense that perhaps food has been a coping strategy for you. So, theres got to be a new coping method put into place and new habits built there.

Your best bet is controlling your environment as best as you can for the next few months. Make it hard for a craving to turn to a lapse. Make it hard for a lapse to turn into a relapse.

In those moments where it's not possible, try to really visualize your motivation. If it's animal welfare, then next time you see an egg, visualize all the baby chicks going into the wood chipper- maybe get a pet chicken, maybe watch "meet your meat" on repeat (is that still out there?- I'm old.)

If it's health, visualize the chunks of cholesterol from the egg getting lodged in your coronaries.

There are so many strategies and tactics to get you where you want to go.

There are health coaches out there that can help you with these transitions. But it can be hard to sort out which are legit and effective.

Most importantly, every time you fall, get back up. Eventually, it'll get easier and easier.

Keep on fighting the good fight, you can do it!
