Add water, honey, and lemon juice to a small pot and whisk well. Add cinnamon stick, cloves, and ginger and bring the mixture to a boil over medium high heat.
Reduce heat to low and let the mixture steep for about 25 minutes over low heat. Strain the mixture through a fine mesh sieve to remove the spices and ginger.
Just before serving, pour hot water into your mug and let it sit for 5 minutes. Pour the water out. (This warms up the mug so your drink stays hot for as long as possible. You can also use an insulated mug.)
Add vodka to the mug and pour the honey lemon water over the top. Garnish with fresh lemon slices and a cinnamon stick. Serve hot.
