In a saucepan over medium heat whisk together the lemon lime soda, brown sugar, honey and lemon and lime slices.
Bring to a simmer and let reduce until it is thick and glazy, about 10-15minutes.
Place the ham into the slow cooker and cover with roughly half of the glaze mixture.
Cover and cook in the slow cooker on low for 4 hours.
Remove the ham from the slow cooker onto a tray.
Reheat the glaze on low and pour over the rest of the glaze.
If you like you can place the ham onto a lined baking sheet and pop under the broiler for a few minutes to caramelize the glaze, but that step is optional.
