When I first started taking ambien, I was keeping small grandchildren and my mother-in-law -- she was 96 and it was no easy task -- i was so tired at night, I asked my dr for something to help me sleep -- he gave me ambien--after taking this med for a year, I was a total freak -- yelling at everyone, talking ugly to husband and mother-in-law, irritable, shaky,trembling, anxious, memory loss, nightmares, depressed, to name a few -- I continue to have these problems even though I have been off the drug for a year -- as a matter of fact my trembling, anxiety, fast heart rate, coordination loss (am now using a cane to walk) cant keep my balance, I hardly ever get out of the house--my question is--will these side effects wear off or am I going to continually get worse??? thanks for any help
