"i started taking saint john wort a week ago. i have bad anxiety with slight depression, but its being looked into if thus could be ptsd as i have flash backs, fear of leaving the house alone, a lot of trouble sleeping, mild panic attacks the list goes on. anyway, i have been sleeping easier without that groggy drugged feeling you get with sleeping tablets. i have been calmer and for 5 days haven&#039;t felt overwhelmed with fear. i have been relaxed enough to go to the shop alone. i don&#039;t feel as down. i&#039;ve also been taking b12 in the morning so have a bit more energy to. i will say though i don&#039;t like the taste, it stinks and i have noticed my hair has gotten greasy really fast? oh and i&#039;m not smoking as much, just don&#039;t fancy one as much now."
