This could also be true for other remedies but I tried lavender oil for the first time last night. Put it on a tissue and slowly inhaled the vapours. It made me very sleepy. Then i took my my 50mg of seroquel and within 10 mins I was so tired that I couldn't sleep, if that makes sense. Everytime I would close my eyes as soon as I started to drift off I was awaken with a "jolt" of some kind and my whole body would twitch. Kept happening for hours and finally had to take a Xanax to knock me out. In hindsight I didn't realize lavender oil was this strong and wouldn't have combined them.
