    I really like this

    I've used this tryptophan for about 5 years. It's the only thing that gently helps with the insomnia that I deal with and I noticed it helps with restless legs as well. I take one at bedtime. Sometimes I need to take 1 or 2 more through the night as needed. It seems to work better/quicker if I drink 4-6 oz. of water with it.

    definitely helped me sleep

    took before bedtime, regularly. Now I use it sporadically. Definitely helps.

    I try to have it always on hand.

    L-Trytpphan works for me, I've been using it since 1981 on and off. It helps me with sleeping at night and my daughter takes it for restless legs. I take 2 an hr before bed and two at bedtime...
