Stopped taking lorazepam Tuesday, after weaning off for 12 weeks. This is day 5 without. Really bad tremors, no sleep, nervous, feel weak. What can I take to help me with this? My primary doctor is no help. Also have heart palpitations. The pharmacist suggested melatonin for sleep - it helps a little bit. Open to any suggestions from anybody who has been through this. I am 64 years old. Please help as I do not know how much more of this I can take. Thanks to all that answer these problems.
