I suffered a terrible journey with effexor. It was the start of many problems. (But that is MY experience ....)

The extreme agitation you mentioned was one of the things I went through when tapering from effexor. I can imagine that you are going through this after a number of missed doses. It must feel awful!

It will be in your best interests to resume taking your meds and discuss tapering, if this is what you need to do, with your doctor.

Good luck.
