Hey WWI! I'd recommend making sure you're eating plenty of vitamins and minerals and make sure you get plenty of exercise. I know when you feel that tired, exercise is the last thing you'd like to do, but put some upbeat music to your taste on the mp3 player of your choice and go to town on a nice walk or similar. Personally, I found 2 bananas in the morning to be really helpful.
Keeping busy is another thing that helps - so that you don't even have time to notice how tired you feel. I'm not sure if you live in or near a big city, but look up your local Cocaine Anonymous and Narcotics Anonymous groups, make a list of them, and go to as many meetings as is physically possible without being in two places at once. Going to meetings in early recovery is good for sanity being around other sober people who get what it's like to be an addict, and also the shares at every meeting from people help remind you WHY you got sober, and WHY you're better off not using, no matter how you may feel at the moment. You really need to FORCE yourself to do things. The longer you sit on that bean bag, the harder it will be to get up. Remember you're changing your life here - if you were somewhat sedentary before, it's time to change the habits and get more active.
By this point my friend, you are not detoxing or in acutewithdrawal anymore, or shouldn't be, so this is mostly just life on life's terms, so it might be time to cut out the benzo. You may not think that Benzos are part of the problem, but we are masters at combining and substituting one drug with another to get high, and remove the drug of choice, and you may find that quickly benzos become another problem. It's part of the addict mentality.
Also try not to read up on PAWS at the moment or related syndromes. As addicts we're prone to "look" for a problem and then "Look" for a solution and we can think ourselves into rattles, or think ourselves into PAWS. That's not to say your symptoms don't exist, but try not to focus on them, because from what I've heard from a lot of ex-addicts I've met recently, the vast majority of the time, you can psych yourself into PAWS or make it worse by being over-cerebral about it. So the best advice I can give you on top of the above is to STOP READING ABOUT THE NEGATIVE THINGS! If anything, you'll start obsessing over it and trying to guess if it's part of your "Rattle" and you might even use it as justification for relapsing.
You're doing REALLY REALLY well so keep at it and you'll be feeling better soon! I know I'm a little tough love here, but it's really what I think will help. x
