I've experienced the same situation and still do sometimes but not as much as before. I had a lot of hard times sleeping with thoughts coming in constantly to my mind. It was like I wished I can put a firewall in my brain. I used to smoke pot constantly because it relaxed me. Did take occasional sleeping pills but they were causing more damage.I was not able to sleep quickly and when I did it seemed like I couldn't get out of bed.
Anyway, I actually ended up leaving town which did help a lot. Changing settings helps changing a state of mind. I won't lie; the first few weeks were very difficult and I had a lot of mood swings but I kept reminding myself that I'm experiencing withdrawal symptoms so it's normal to feel this way. I would just have to be patient and wait for it to go away. If you were taking drugs (legal or illegal) for a while and then stop, the body will just need some time to adjust itself. I'm sure you know this but it always helps to keep reminding yourself of that fact and that stage you are going through whenever you feel irritated and if you can move out for a while with someone supportive to a different city or country like take a vacation if possible so you can relax your mind.If you still feel you need medication try lowering your dosage bit by bit.
Hope it helps.

Good luck

Excellent advice from Maggie even though it seems 'far out'. Our thoughts do indeed completely control everything about us, from our moods to our perception of the outside world. Sleep disorders and 'thought trains' as I call them, as thy never stop running, is something I too have experienced and overcome in the past. My advice is meditation and visualisation. Google 'The Linden Method' and give it a go; if it's getting you down that myc then you have nothing to lose. It's not a one solution fixes all, but I am confident that if you channel all these thoughts into this method, them you'll feel some benefit. When we're calm and feel safe, and unless there is a true psychological condition caused by an physical abnormality, then you can 'heal' over time, but it will tAke just that. Just remember that sub conscious thoughts are not real, what you choose to believe IS real.

Good luck.

I am 56 years old male and thought the constant racing thoughts were what everyone had. I never considered it abnormal until one of my children talked about not having any thoughts sometimes. I have 2 sons who clam they can just stop thinking and my youngest is like me the thought never stop except when sleeping (then dreaming takes over). The voice I hear in my thoughts does not sound like my actual voice but it is mine, I guess because it's the one I have heard all my life. I have also had a difficult time reading all my life because my thoughts will wander and the next thing I know I either stop reading or I have no clue about what I was reading. Movies seem to block the racing thoughts and make me concentrate on what is going on but I try to figure out the ending during a slow movie. The visual stimulation of the movies seems to be a key. I can get the same relief just walking or running outside and looking at the scenery. Even with this I am a very happy person but I can understand how this can drive someone crazy. I can also understand how some people resort to substances to escape the situation but I had an alcoholic father and brother who loved marijuana and I would not go that route. Weight lifting is another thing I use to focus my thoughts along with the running (I hate to run but it helps). I have been researching this for a couple of weeks and I have come to the conclusion that this is the way I was made and like any other problem we are given I will have to work to control it. Meditation is the next tool I will be trying. I do believe that good nutrition and supplements help and that prescribed drugs only mask it and make you dependent. Good luck and I hope some of what I have said can help. As always I will be thinking about it!

I've had the same problems quetiapine fumarate is the best thing for sleep but I find it can cause a lot of anxiety as well and panic attacks but sometimes it's best to choose the lesser of two evils.
Try to eat well and get your sleep whatever it takes you can't catch up on sleep you need 8 hours a day you cannot sleep 6 one night and 10 the next it's not the same I find when my thoughts are racing it's best to try and not imagine real things for an example if your upset @ someone instead of trying to solve the problem in your head try to think of something funny and instead deal with the problem when it arises of course if your just trying to figure out what's for dinner give in to your thoughts when your minds racing or your having troubles sleeping try not to make any serious choices and take what works best for you to get your sleep.
