Need assistance please!

I’ve been taking phenibut for about 5-6 weeks. I started doing 3g a day, quickly ramped up to 6, then the last 2 weeks 8-10gpd.

I was tapering for 4 days on a fast taper about 1/2 of my normal dose 2x a day. On Tuesday I took only 1,500mg. After that my package got delayed until Friday.

I have been completely cold turkey now for 50 or so hours, nothing but low dose Klonopin which has been helping a lot, but is slowly helping for shorter periods of time, and I’m really scared for tonight. I also do not have many benzos left so this is what I’m wondering;

When my package comes I want to finish the actual taper I started. Where do I start since I’ve been off 4 days?? How do I know what dose is right?
