Hello sir/madam 8 months ago I slept in bad posture due to which I got dizziness. My doctor advised me to take lonazep 0.25mg. I took the medicine for 6 months then as per the advice of doctor I started taking half tablet for 20 days then quarter tablet for next 20 days. Now I left lonazep completely from last 15 days. But now I am feeling lighthead, vibrations and jerk in my head. Also these problems occur at night. Some times my heart starts beating very fast and it can be observed in head also. These all problems mainly occurs at the time of sleeping. My all reports are fine. I have done with MRI brain, MRA neck vessels vitamin b12LFT cervical everything is fine. Only vitamin d came little low. Please guide me what is the problem and what can be done
