Have you tried a high CBD/low THC strain?
When I found it was limiting me, I moved over to a strain of this type and it still satisfied my urge to smoke something tasty, but also did not hold me back from doing anything, as it these strains do not get you 'stoned' in the normal sense. In hindsight, my addiction was that I related the act smoking to sitting back and being lazy, so once I removed that link I no longer felt the urge to smoke and I rarely smoke anything these days.
I recently read a book called 'The Power of Habit' which offers amazing insight and ways to help you overcome any addictions and in a much more efficient way...I highly recommend it!
Yeah basically just sort yourself some Sativa instead of Indica. It's almost like a whole new drug. I much prefer it, plus sex on it is utterly amazing.
Sativa is still usually high in THC, it just has a different high. However, I still found even Sativa strains would give me 'couchlock' most of the time! It is the third strain 'Ruderalis' that has a high CBD content and low THC.
If you are lucky enough to be able to grow, i'd advise trying a strain by the 'CBD Crew' who specialise in these high CBD strains. Med-Gom was the strain I tried so I can certainly recommend that one :)
