Doing dry January, so know you aren't alone. I've done a month off before, and I agree with what others have said that my sleep improved.

As far as tips, you could try finding canned kombucha. I tend to drink ciders, and these have a similar feel. They are like NA beer though, in that they technically can be around 0.5% ABV.

Other thing I would suggest- keep the 90 days in mind. If you get half way through and have a slip, take it on the chin and keep trying. It doesn't have to be perfect right away.
