What are your panels? Do they all have three years of data? Please describe the population sampling process. How did the sampling produce different weights between years?

Dear all
I am estimating a 3 year panel (random effect) using survey data. To get correct estimates I should use sampling weights, but the command xtreg, re does not allow me to use weights...I can use xtreg with the option mle, which allow me to use analytic weights. But stata requires weights to be constant within panels. Is it correct to use the weights of the last year, and assume they are constant within panel?
Or should I simply ignore weights?
I really appreciate your help,
Manuela
