"i have been on 150xl  and feel horrible. its almost like i&#039;m tripping on lsd. foggy head, angry, cranky and very irritable. heart palpitations and it makes me very lethargic. dr recommended taking it at night and its a tiny bit better. i want to stick with it to see if it gets me to a better emotional state but don&#039;t know if i can last. how long before i start feeling better?"
