They're temporary. You can greatly reduce their length by eating well, being active and pursuing things that make you happy, and exercise. Getting in shape and working out some every day helps SO MUCH. I think part of PAWS (not all of it) is more mental than it is physical. You have to progress your life beyond your addiction. Figure out what you were using drugs to hide from or cover up or deal with, and fix those things in your life. Fill your time with new activities that interest you and make you feel happiness. There is definitely a physical element to PAWS, it's your body returning to normal after relying on drugs to be normal for a long time. But that fixes itself. However, if you never improve your life situation, you may continue to feel bad. Stress, anxiety and depression cause physical issues in people by themselves.
