I agree with @Upstate on Oaxacan strains. My brother in law calls them “working man’s weed” because it relieves physical pain, gives you a lift, makes life sunnier and motivates you. I’ve found that of all the herb I’ve worked with, it’s the one genetic that I can smoke all day and keep my wits, energy while still feeling high.
I’d definitely recommend Kratom as well. It’s addictive and will give you withdrawals like opiates, but it’s easier to manage. Keep your dosing 5 hours apart (more is not more when it comes to Kratom and the two different opioid antagonists), switch strains and keep your total usage under 6-8 grams a day and you shouldn’t have issues. Take days off and taper a bit when quitting, but it’s a lifesaver for a lot of people.
