Im taking 50/50. I started on 10/12.5 however and that got me off the max tramadol reducing by 1 tablet per day each fortnight.

I also use tramadol: 200 mg ER as my base medication for chronic pain & also 50 mg for immediate release when I have flare ups. I did at one point wean myself off of tramadol so I could use medical marijuana. For me, yes, MM, once you find the right ratio from the right indica/sativa/hybrid for you, works wonders. For my pain mgt, it is much better than any opiods out there. BUT.....it was costing me about $400 a month for MM to have same level of relief that $60 a month for my combined Tramadol.

I like a 1:1 ratio but the strain will matter too. I started with 5mg but I also take lyrica for my nerve pain.
