Benylin Insomnia Causes and Reviews


Insomnia is a common sleep disorder. If you have it, you may have trouble falling asleep, staying asleep, or both. As a result, you may get too little sleep or have poor-quality sleep. You may not feel refreshed when you wake up.

Symptoms of Insomnia include:

  • Lying awake for a long time before you fall asleep
  • Sleeping for only short periods
  • Being awake for much of the night
  • Feeling as if you haven't slept at all
  • Waking up too early

Your doctor will diagnose Insomnia based on your medical and sleep histories and a physical exam. He or she also may recommend a sleep study. A sleep study measures how well you sleep and how your body responds to sleep problems. Treatments include lifestyle changes, counseling, and medicines.

Benylin Insomnia Reviews

Fri, 28 Jan 2011

After several small sips of Benylin DM-E ( regular strength), an episode of transient global amnesia.
Same had occurred many years earlier after absorbing a number of throat lozenges on an airplane

Mon, 12 Mar 2012

I took 7.5ml of Benylin Mucus and Phlegm which is less than the recommended dosage for my age (39 yrs). I did not sleep all night, my eyes are puffy, my vision is blurred caused by a thick discharge in both of my eyes. Never have that before. Its the LAST TIME I TAKE BENYLIN.

Fri, 17 Jan 2014

I took the night time version and now I am wide awake 4 hours later, every time I am about to fall asleep my throat starts twinging and a coughing fit follows. Without the drug I don't have this it has also caused disgusting discharge from my eyes, a horrible headache and tightness in chest.
I would highly recommend NOT taking this product it is horrible and I have a feeling has probably caused serious damage to my bronchial tubes with the amount of coughing its causing.

Took it, didn't know it was the "drowsy" kind, went shopping and felt like i was drunk

Thu, 11 Nov 2010

I took Benylin the other night and I could not fall asleep. I was awake in my dream, or my hallucinations. My husband woke me up and my hands we crippled up and I could not move feet. He took me to emergency, as I thought I was having a stroke. The drs said it was probably a reaction to Benylin. I am 58 yr female, healthy and I do not take any other medications.

Took the prescribed amount for my age. Did wonders in getting rid of my cough but was to busy enjoying the hallucinations to feel the relief. Took it once. Won't take it again. I like being in reality.
