Taking lunesta to sleep while weaning off of Valium? Safe? GABA ?

I’ve been weaning off of Xanax and now Valium since April 2024 after an 18 year habit of Xanax prescribed by my doctor my new Doctor Who is a psychiatrist put me on lunesta to help with my insomnia as I’m down to 1.5 mg Valium which is a super low dose. I have been reading you shouldn’t take lunesta while weaning off a next due to the effects on GABA. My psychiatrist says it’s fine..has anyone taken a sleep aid like lunesta or ambien while weaning off a benzo? Please help if you can! I can’t tolerate Hydroxyzine or trazadone as they dry me out too much and don’t make me sleepy either..I’m at a Loss..thanks
