I'm glad you're taking such a cautious approach. Some people choose to taper the most activating drug first. Since you take the Fluvoxamine at night, does it help with your sleep?
Liquid versions are more convenient if you need to make tiny dose reductions, but any drug can be tapered by using other means such as bead counting or shaving pills and then weighing. If you go to the Tapering Protocols section of the forum and click on the Guides tab you'll find lots of helpful articles and information.
Here is some clinical information about both drugs:
