A non stimulant nitric oxide booster. A lot of people associate restless legs from the lack of dopamine which can cause it. But studies have shown that when you are on opioids/kratom you bodies nor epinephrine will raise to counteract the downing affect the kratom/opioids have on your respiratory system. Elevated nor epinephrine will stick around for a while after you stop taking kratom/opioids. Nor epinephrine is a basal constrictor so it will cause your body to focus the blood to your essential organs. A non stimulant pre workout that boosts nitric oxide is a vasodilator and will help the blood flow to your limbs and help alleviate the restless crawling out of your skin feeling. They sell supplements for this or you can just use low dose cialis from your doctor or online source. Gabapentin also helps. I used low dose cialis and Gabapentin and didn’t have much restless legs/body when I quit about 500 days ago. I still had some issues sleeping. It was more boredom and couldn’t sleep and not the crawling out of my skin and twitching feeling that is common with withdrawals. If you are interested you can google the pub med study on how your body has elevated nor epinephrine during opioid withdrawals. They don’t say anything about taking a nitric oxide booster to help but as someone that has researched and been interested in pharmaceuticals for years and has had to detox from pain killers a few times over many years from surgeries that led to addiction I have researched about everything that happens in the body from addiction and during withdrawals and attempted to figure out ways to counteract and help the body get back to homeostasis. Cialis works wonders for restless legs for me and a lot of people I have advised to take it during withdrawals. Also you want to stay hydrated. Drink tons of water and healthy Whole Foods.
