Well, I got some L-tyrosine from NOW brand in the powder form and started taking it today.  I noticed a change within minutes of taking it!  I felt like a high and have had a calmer mood all day.  I also got tickled and was laughing many times throughout the day, one time almost hysterically laughing!  My hubby was looking at me like I had lost it!  It was SO fun!

It did not make me sleepy like the Catechol, but did make me more relaxed feeling.  I also only got 5 hours of sleep last night and am not really tired at all.  It is 9 p.m. here.  I was much more laid back with my children today, it just took an edge off of me or something.

It is pure tyrosine, nothing else though.  Any concerns with that?  Should I take it with something else?

A Happy Camper,

I took that for a while, I got it from GNC. I sure didn't have your type of response with it.
