Hi Pravchaw,
I don't think it is a problem to spend time on SR--educational, sustaining, enlightening. And you will know when you need to cut back!
I am glad your son came around, though I am sorry it didn't go so well. It is really hard to let go of what we had hoped for our children versus what they choose for themselves, especially when drugs are involved. Just keep working on loving detachment. And maybe try to let go of the college thing---I am having to do that right now, so perhaps you & I will just keep in touch about that with each other and try our darnedest to not interrogate our kids about it! Take care.
