Sleep apnea is what i always ask if the person is having sleep problems like yours-i was saved a lot of sleepless nights as i was diagnosed with sleep apnea and use a machine to breath through during sleep. you need to be tested for it if you decide. Also chamomile tea always worked for me too. I realise you're going through withdrawal which may be the only problem i hope you can do it I'm rootin for you to do the best thing you can do and re doing by giving up all the drugs etc... I am so proud of you!!!!!!!!!!
