Indoor, potted Honeysuckle losing leaves, (spotted, yellowing, & curling) too much, too little water, or ???

I bought this honeysuckle from Home Depot this summer & it did well while in the temperate mountains of Arizona, when we moved to the desert in Sept, it survived the high temps ok until we moved it indoors for the winter. It's in an extremely well lit alcove now, but the brown spotting, yellowing & curling of the leaves that it has always struggled with is now defoliating my plant. Currently, in anticipation that it may be root bound (until I find a bigger pot for it) I have been putting ice cubes on the top of the soil so the slow melt allows the plant to absorb the water. I've tried this for 4-5 days, no help yet. Any other ideas?
