There is a short term “withdrawal” normal and a longer term “life feels normal again” normal, and both take time. For many people, the rough physical withdrawal starts to ease within about a week, and the first month is when sleep, appetite, and energy slowly begin to level out. Emotionally and mentally, it is common to feel up and down for several months, with most people noticing a real shift toward feeling more like themselves somewhere in the 3 to 6 month range, while deeper brain and mood recovery can keep improving over a year or more.
