    better than valium with no drugged effect
  

*by B***X on Reviewed in the United Kingdom on 15 November 2021*

I have always been unable to cope with life in general especially after suffering from a nervous breakdown .  I became addicted to valium back in those days when the doctors gave them out like smarties to anyone who was anxious.  I took them for 12 years.  horrible withdrawal for 6 weeks and since then have managed on G.R. Lanes Quiet life tablets during times of stress.  When these were discontinued, I bought the necessary  'Quiet Life' herbs and made up my own 'quiet life' herb mixture to take as and when needed.  Not as good as 'Quiet Life' tablets, but acceptable.  Taste is awful.  but then i read about l-Theanine and decided to give it a go.  My son has divorced recently (his fault) and through the trouble which ensued lately, I have been getting those chattering thoughts that you get, especially at night, when you cannot resolve a stressful situation.  You know - the scenarios and what shall i say to this person or that person, etc.  I try to pray but the thoughts go on.  So, I took 200 mgs of this instead of the 400mg and within 30 minutes, the thoughts just dwindled away and my heart rate slowed to normal and i just dropped off to sleep.  During a similar incident concerning the divorce, after a nasty email the other day, I was in  shock and shaking.  I took 200 mg then and within 30 minutes I was calm.  100,000,000  stars and will keep these in the house.  In the  past 6 years 5 of my family died - 2 of them suddenly and 11 months apart.  God helps marvellously in these situations and reminds me that it  is only the body that dies but the soul lives on, but we still have the bereavement to go through and missing them terribly.  I wish i had l-Theanine during that time.UPDATE 28th October 2022My sister has just died suddenly.  At present we are waiting for the coroner to tell  us what she died of.  She used to put peoples bins back in their gardens after the dustbin men had been.  Her neighbours saw she hadn't done it last week and that her curtains were still closed in the day, so when they noticed her lights didn't go on in the evening they broke into her house and found her dead on her bedroom floor.  Her face was mottled.  My other sister visited her once a week and 6 days previous to  her being found, so she had been dead a few days.  The shock was terrible.  I took 1/2 a capsule of Theanine and it worked as above.  but i found that 3/4 worked better.  I took 3/4 capsule three times a day for the first 2 days and some for during the night when I couldn't sleep.  For 3 days the shock was intense - the first night I slept on and off - the  second night were racing thoughts and memories mainly of how Julie was stressed and angry and all the negatives about looking after an elderly relative for years without respite - and the thoughts wouldn't stop and my heart raced as I was bordering on a panic attack.  So, at 3.15 am,  I took 1/2 capsule and within  30 minutes the thoughts returned to normal as did my heart rate and sleep took over.  Day 3 and my joints all over my body felt as if i had been beaten with a hammer (RA) due to the inflammatory reaction which comes with stress and shock coupled with the fact that i had no comfort from the above mentioned son - no words - phone calls or email.  Now i am taking 1/2 capsule 3 times a day and i feel calm and focused.  The shock is gone mainly.  Today, although still a little anxious about the coroners report, I can cope extremely well and without the fear that all this brings.  I am writing this as I think that anyone out there who is suffering from bereavement or awaiting the death of a loved one should take this as it really works well.  I can't sit here and not try to help others who are suffering this  awful thing.  For those who  are caring for sick loved ones  and are feeling the stress, this is a life line.  You can function normally as if there isn't anything wrong.  No drugged feeling.  Nothing like with tranquillisers that the doctor gives you where you just want to sleep.  No.  just normal and calm in the daytime but great at giving you sleep at night.  I feel Julie is living in the light of eternal springtime and peace now and the memories i have of her is when she was smiling and happy and light and young. 500,000,000 million stars.

I have been buying these for years. They help, a bit, with my sleep but generally make me feel more alert during the day
