How many months did it take texas to consolidate its independence from mexico?

It didn't happen quickly. 40 months at least. As I recall hmm Cos maybe, Wol? invaded and occupied San Antonio as late as 1842, defeated at Salado Creek. Gave birth to the disasterous Mier Expedition into Mexico. In fact, I believe the Snively Expedition raiding trade on the Santa Fe Trail happened in 1842, also.
