Meth recovery works. It also takes time, and knowing the shape of that time protects you. The first days bring the crash, when your body demands sleep and rest. Then come the flat months, where motivation and pleasure feel far away. This part is normal. It is not a sign you are failing. Slowly, feeling returns. Food tastes like something again. Sleep steadies. You start to want things. Expect this stretch, and you are far less likely to relapse when it comes.
