Hi there and Welcome to HealingWell!
The dosages of 5-HTP vary from person to person based on a lot of things such as weight, gender, level of depression etc... so advise regarding the dosage is difficult. Have you spoken to a physician about this? I havn't used it myself but a member of my family has and found it to be very effective. They found that it was helpful as it allowed them to go through therapy much easier. Hopefully there will be others out there who will share their story.
I hope you find the support you are looking for here and that everything works out well with your 5-HTP. Let us know how you get on
