I had only slight nausea when I first started dropping my dose but I think that was me getting used to the inositol.
Once I was down to 22.5mg of mirt, with no withdrawal symptoms, I figured I could go a bit faster and dropped my dose down to 15mg.
I had no withdrawal symptoms after ten days and so have now dropped my dose to 11.25mg.
I use a simple pill cutter from ebay to cut my tablets. Mirtazapine had pooped out on me and so I already have terrible insomnia.
It is used to sedate excitable or difficult horses that are on enforced rest.
