I've been struggling with pretty severe chronic fatigue / fibromyalgia symptoms since we moved earlier this year. I've actually been taking L-Tyrosine for a while, but really hit or miss. I didn't know what it was supposed to do. I looked up the info and was amazed. It's a naturally occuring amino acid and it helps fibromyalgia, depression, chronic fatigue, having energy after sleepleness nights, and other things. Here's a link for information. I think it's available at WalMart or just about anywhere else. It's called L-tyrosine. I've been more purposeful about taking it and am feeling much better. My daughter even said the other day, "It's good to have you back!!" It's good to be back...
WebMD article about Tyrosine (update 9-22-14: It's still a decent article, but they seem to have removed some of the original information they had.)
This article is not one I originally read, but it has the information I remember from the original articles I researched. I hope this helps: Article about l-tyrosine.
Here's my referral code for PureFormulas if you want to order online. They are very reasonalble, have excellent quality products and free shipping. Here's a pic of the Now brand Tyrosine.
Also, I'd like to share information about another helpful product for people with interstitial cystitis. I've had success with aloe juice and so has my sister. She takes it for kidney pain and Crohn's disease. It helps with urgency and seems to help with other symptoms for people. I use just the inexpensive Fruit of the Earth brand from WalMart.
...just thought I'd pass along some helpful information!
Blessings,
Sharron
