Trial court judgment revoking and terminating defendant's probation is affirmed where: 1) the court properly imposed an aggravated term as the court was strongly in favor of the aggravated term even before the new violations were uncovered and defendant was given several generous opportunities over an extended period of time to address her substance abuse problem, to cooperate with the probation department, and to comply with the terms of her probation; and 2) the record does not support defendant's claim that her waiver of Penal Code sec. 4019 credits was not knowing and intelligent.
