Plates are lovely!!
I think the little goals You have set yourself are great little motivators.
Tbh is like You say. It's best to get out the habit of drinking most nights. Because it's loaded with sugar so can't help the losses. But every now and again is Ok. Don't deprive yourself of something you want else You will want it more.
It would be great for you to get back to a number you haven't been to yet on the scales. You know how to do the plan. You Just need your will power button on full. Lol x x
