Mixing pills and liquid

Hi -

I have a couple questions about mixing pills with liquid. I'm on 3.5mg Diazepam right now, and have decided to start DLMT with the .5, and take the rest in pill form.

I was thinking to do a 21-day taper for the .5mg, slowing down at any point if I need to. The instructions I've seen here have been to use 100 ml or above in solutions/suspensions. Questions:

Is it ok to make a solution/suspension that has .5mg Diazepam, 1 ml vodka or PG, and 20 ml of water (21 ml total)? And then take 1 ml out each day? Or is it important that the solution/suspension be more diluted by water?

Thanks so much.
