I recently had an MRI with anesthesia. The doctor advised me to stop taking my .5 Ativan at bedtime because it delays the anesthesia withdrawal. He said the dose was so small that stopping it would be a no-brainer. Doctors tell me thing slick this without realizing how sensitive I am to meds. I did stop and then started taking .25 at bedtime The thing is- since I did this I cannot sleep. Like hardly at all. Can stopping it this way cause a rebound type of insomnia. I certainly hope so cause I am a mess. Please share any insights or experiences.
