My bearded dragon is acting like shes drunk?

she stumbles when she climbs her log like she is drunk, i don't think its leg paralysis because she moves the when she walks, she hasn't had much of an appetite yesterday or today, she's bout 9.75" long and she ate about 12-15 adult crickets on wednesday. yesterday she pooped twice and she threw up about a cricket and a half. the temps in the cage are 104 on the basking side and 80 on the cool side (measured by digital thermometer) she doesn't seem to be lethargy, she hasn't eaten any mealworms that i put in the cage. she has a basking light but i got the wrong UVB so i have to get another, does it matter much if she doesn't get the UVB until about the 1st? i just got her on the 20th. any suggestions?
