I've been using 5-htp for a couple of weeks now - with great results!
I noticed that a previous post says that it makes you sleepy. That is *not* true. I was worried about the same thing. As far as I understand it 5-htp helps the body produce serotonin. If it makes extra, it just stores it. Then when you are ready to go to sleep, it utilizes it. I have been taking 2 tablets three times a day - for hypoglycemia! This wasn't recommended to me. My fiance got a book which recommends 5-htp for depression and obesity. The questionaire to determine if 5-htp will help you for weight loss sounded a lot like a questionaire for hypoglycemia. It is really helping me. It's incredible. My fiance is taking it for depression and we both had immediate good results. My fiance's 11-year-old son also suffers from depression symptoms, and the 5-htp is helping him, too. I would say that I am pretty happy person, and it just makes me even happier. A lot of the time I feel like I am on the edge of a smile :).
One concern is that it can cause nausea. I find that it is very important to take it with, or just prior to, a meal. I have had some pretty severe nausea, but the results are so good that I will not stop taking it. I just had to figure out how to use it right. I think that you should start by taking 1 tablet three times a day with a meal. If it seems like you need more you can gradually increase to 2 or even 3 tablets three times a day. The gradual increase is so your body can get used to it, in hopes that you will not experience the nausea. The best option is to find some encentric coated 5-htp. Encentric coated 5-htp will not dissolve until is reaches your small intestine, so there should be no nausea.
One more thing. The place where I used to work gave 5-htp to our clients who had trouble sleeping. One tablet at 5pm and one at 9pm. They also gave them a b-6 tablet with the 5pm dose. I guess the b-6 helps the 5-htp to work. So, I have been taking a b-complex with my morning dose. B's are great for mood :).
