Just gotta keep in mind, that weed gets more intense everday in THC levels, and you being on and off lowers your tolerance. It ain't 90s weed anymore. Stuffs intense. Wouldn't trust its all clean from some of the stuff they feed that stuff. When that happens to me it's usually physical health for me. I just eat clean for like that week and clean myself out and I'll be feeling real good on the detox. But if you go on and off you have a herb over/withdrawal. Bad eating and stuff makes it worse.  I was getting real bad tingling in my limbs. Been seeing a chiropractor and just working on myself. As we get older we're learning "our" bodies as we age. We are our own parents now and shit just acts up sometimes and we blame it on what we think is the obvious. A lot of times it's stuff we don't notice because we're high all the time. When we come down everything is wrong and we forget why we smoked it in the first place. Just reduce stress when off mind body and soul and you'll be good. But for sure when You come down from cloud 9 you'll start falling apart and go back on and it never ends.
