It sounds like you have access to different strains, so try mixing them up.
I have a lower THC sativa for mornings, which gets me thru the day. I have a hybrid for around 5pm, which is like having a few beers after work. Then I have a strong indica for bedtime.
I’ve been on prescription opiates for years for a bunch of conditions, and while I do get a buzz from it, it’s not what I’m chasing and it settles quickly.
Also, worth considering how you smoke it. I vape in the morning and in the evening, and then a pipe before bed. Each hits differently, and works well for me. Might work for you too.
No worries. They each have newer models out, but I have no need to upgrade from what I’ve got. Have a look at video reviews comparing each to their newer models and decide what’s best for you. You can pick up the older versions cheaper if they’ll do that job.
The mlfb isn’t bad, it was my first dry herb vape, but these are miles away a better option.
