What withdrawal looks like from the outside
It rarely looks like “getting better slowly.” It comes in windows and waves: a good stretch, then a rough one that seems to arrive from nowhere. From where you stand you may see irritability, tearfulness, a short fuse, fear that seems out of proportion, trouble sleeping, or days so flat and low they look like relapse. They are usually not relapse. When the brain has adapted to a drug, lowering it unmasks a nervous system tuned to be hyper-excitable for a while, and that shows up as exactly these symptoms.
A bad day is not a failure of willpower or a sign the plan is wrong. It is part of how recovery actually looks. The good days will keep coming back, often before the person going through it can feel that they do.
