I have the same problem - not with my diamond studs (I wish they were large enough to give me that problem!), but I do with my South Sea pearl studs. I tried to clear plastic discs, but they could be seen (I have small ear lobes), but then Japster (got the earrings from her) sent me the larger size gold backings - those work pretty well, but I check them during the day when I wear the earrings to make them tighter...they migrate during the day and start to droop...
