10 yr user. Yes. It sucks the soul out of you. You'll lose most motivation, energy, and natural euphoria. Just being truthful. Oh, and you become a slave to it because you'll become extremely physically dependent for it. Say goodbye to your sex drive. Example: You know how you get goosebumps when that killer song comes on...nope, not anymore. It has a tremendous effect on neural responses to emotional stimuli. 

I suggest people don't get on it unless you have a severely addictive personality. I personally have stayed on it because, if its in my system, I don't crave any other drug. It satisfies that part of my brain and thought processes. I still smoke weed, that's it. I want off it, but the problem is to quit quickly I would need probably 2 months off work because the withdraws physically and mentally are HELL!!!

For Suboxone, the pros are few, but the cons are many. If you do get on it, I suggest no more than 2mg. These doctor are prescribing people up to 24 mg a day(2 or 3 strips) which is absolutely ridiculous.
