No Specified. And I know you know that. If you are suffering from heart failure your heart needs some tender loving care. That is not to say it can't heal and down the road play around once a certain amount of healing takes place. (doubtful but trying to give you motivation to help your heart) But right now your heart is telling you it needs attention.
The longer amount of time you put in between these stimulants the less the desire will be there. Of course in the beginning a drug addiction is like a black hole always sucking you in. But the truth is after some time it fades. So in time you will feel less like using stimulants. If the obsession did not fade nobody would EVER get off anything. It fades and fades.
Let me say it, heart failure is not good. Not as deadly as it once was but certainly in a serious category. I feel like stimulants will land you in the Shrine right now. And the world can use you right now. You got 5000 posts and I have been reading you for a few years. So any drug you indulge in should not effect the heart if you want to keep healthy. Not sure that is opiates and benzos (of course if it were me I would try that) but your heart gave you warning.
I wish I could take the desire from you. Hey I read BL too, and I would love to try meth but I am too old. That I know. Glad I missed that boat. I will abstain and you abstain too.
