Currently new to DXM. Reach the 2nd plateau several times within a couple of weeks. Decided to reach the third(weigh roughly 155) took 600mg, sat on my bed played some music, didn't feel far from the 2nd in which i usually take around 300mg. thoughts were a bit stranger not too many visuals, basically felt like on 2nd plateau. Decided 4 days later to double dose. i take dose, kicks in about an hour later, which is the normal time. Starts slow i sit down listen to ambient music, hoping for visuals. I felt exactly the same as i did when i took 600mg. I am really disappointed because i was hoping for some type of oobe, which is why i started in the first place. Am i doing something wrong? Did i take too much in the amounted time? Should i up my dose?(taking generic CVS 15mg dxm only pills(20 a bottle).
