Former meat lover here. Just keep going.

I kept reducing meat to a point where once I had it after a long-ish hiatus... I realized I don't care for it anymore. Meat substitutes or meat free meals can be just as delicious - and guilt free! And these days there certainly are many options available compared to say 10 years ago.

People who can do the switch over night have my greatest respect - but if I tried it I'd fail miserably and just get demotivated. And even if you don't manage to switch 100% - honestly that's still better than not trying at all.
