i have taken 5htp ,i experimented with different dosages i like the idea that it increases serotonin i used to take it at night 50 mg used to help me sleep i combined it with sjw the sjw made me very groggy so i dropped that,the 5htp didn't remove my depression fully but it helped me sleep and reduced anxiety,i had no side effects at all,unlike prescription ones.i am going to try taking one in the am instead of at night.
