I have taken 50 mg every night for about 4 years.  Last week I decided I need to get off and started the weaning process, cutting back by half to 25 mg/night.  This is day 7 and I feel AWFUL - extreme dizziness/ light-headedness, muscle weakness, insomnia, anxiety, mood swings, crying spells, chest tightness.  This morning I felt like I was having a heart attack.  I want to stay the course.  Any hopeful comments?
