All of this. Not trying to fight it alone would be (is) central to my plans for recovery, get support from everywhere and anywhere you can.
If you're doing it completely unmedicated, there are certain meds you can take to ease the process, but given you're already half way through it's probably a bit late to be obtaining them. Obviously they carry their own set of risks though and you have to be careful.
What are you detoxing from? If it's a short acting opiate then at the four day mark the symptoms should have peaked by now, or just around now, and willl be starting to subside.
