I agree with strawberry that dropping a dose once a week or every other day is not necessarily the best strategy, this definitely didn't work for me. I was told this can actually cause peaks and troughs of the drug in your bloodstream and is not a smooth, gradual transition. It does depend on the half-life of the drug. Those with long half-lives it doesn't matter so much, but short-half lives the every other day strategy just doesn't work.
It is amazing how GPs are often quite ignorant of this fact. Also they think that just because you are on the lowest dose of a drug that therefore means you can just stop the drug. No way! It took me 6 months to get off mirtazapine (and I was only ever on the lowest dose). Thankfully doing it so slowly I was mostly withdrawal effects free.
One thing I would say is that it is not necessarily that easy to get a drug in liquid form. It is much, much more expensive for the NHS and most doctors / pharmacists are reluctant to do this. Particularly as the liquid forms are usually pretty "unstable" i.e. have to be used within a certain short timeframe, and usually have to be stored in the fridge, which, when you have small children around, is not particularly secure or safe.
I got quite skilled at cutting my tablets myself. Another thing I found helpful was to store the tablets with some vitamin pills. Take a vitamin pill at the same time as the AD, then gradually when you've stopped taking the AD you continue to take the vitamin pill so "fooling" your body into thinking you are still in the same routine of taking something.
I hope this helps someone. Best of luck, you will get there in the end.
