Recently I wanted to increase my body's growth hormone production to repair stressed muscles. I read in a book on physiology that people who don't sleep well do no release enough growth hormone in the first few hours of sleep to repair the stress of muscles caused during the day. The book pointed to studies of taking the amino acids L-Arginine and L-Glutamine an hour or less before going to bed.

So I bought the two amino acids (500 mg strength each) and took one of each. I got the muscle repair I wanted. But something else happened - I SLEPT THE WHOLE NIGHT THROUGH! And I have been sleeping soundly since.

I think this works like a two way street. Insomniacs don't release enough growth hormone: Increased growth hormone release causes sounder sleep.

Also you don't have to take Arginine and glutamine every night. Just 3 to 4 nights a week (I know this because I sometimes forget to take the capsules). So it works in a Ted kind of minimalist sort of way. I appreciate that Ted from Thailand is a minimalist in supplement taking. It's refreshing advice.

I have been taking L glutamine before go to sleep for the past few days. And I cant sleep the whole night. My eyes are wide opening. And alert through the night.

I cant think of the reason why I cant sleep. I have stopped already but still not yet can sleep. Is it because I didnt take L arginine together?

Can you please advice me? I hope I can survive in these few days without sleep.

thank you

I don't know if this will help... but, I started taking L-Tyrosine awhile back. I would take 100mg at night, usually with dinner (I weigh around 180lbs). It really helped me sleep... Within a couple hours I would begin to feel really relaxed. Once in bed, I would fall asleep fast. I actually fell into deep sleep faster than I ever have in my entire life. However, it wasn't as easy waking up either. I felt so relaxed in the morning I didn't want to get out of bed. Which is why I stopped taking it. But, it really helped me through a tough time. I would also try some camomille tea... I have a comomille, mint, lavender tea that really helps me to relax before bed. Something warm in my stomach always helps.

I would suggest you to try homoeopathic remedies for insomnia for a long lasting relief. These remedies are prescribed based on the constitution of the person. They work on our body by calming and strengthening the nerves, slowing down your thought process and relieving your anxiety, helping you fall asleep more easily and improving the quantity and quality of sleep which will keep you refreshed and energized. Some of the frequently used remedies for the treatment of insomnia are Sleep CM INS formula, C35 INS formula, C55 neurocalming formula, etc.

People may have to avoid arginine if they have cold sores or herpes. Glutamine can also be a problem in high doses in people who are gluten intolerant.
