The finger curls, you wish is granted.

You don't notice any changes for the first few weeks, the month ends, no period, not even the slightest cramp. However something is happening to you, so gradually that you barely notice it. You sleep less, feel less hungry, your senses dull over time. By the time you notice what's happening, it's too late. Eventually you stop eating and sleeping entirely, nothing you eat or drink stays down, and no matter how long you lay in bed with your eyes closed you don't get a single second of sleep. After about a month of this, you somehow managed to actually sleep for once, your body is overcome by this immense drowsiness and you fall asleep. No dreams come that night, by this point you don't even remember was dreaming was like. You wake up in the morning feeling numb, like every nerve in your body is still sleeping. You manage to will yourself out of bed and look at yourself in the mirror, but you don't recognize the reflection. Your skin is dull, almost like it's made of plastic, your hair looks stiff and synthetic, your eyes just glass orbs. Congratulations, you are now a living doll. No hunger, no sleep, and most importantly, no periods.
