Hi PoppyAbby, I think it would be wise to hold for the time being. Even at 2.5 mg, your serotonin receptors are still being blocked by 48% from the drug. Here is a SERT Occupancy chart for Paxil:

Most of the changes in serotonin receptors happen at very "low" doses, so it's best to try and taper down as low as you can before jumping to zero. However, it all depends on what your nervous system can handle. Everyone is different.
Venlafaxine (tapering) - Current dose 17.92 mg
Trazodone - 50 mg
Levothyroxine - 25 mcg
