VERY weak from my experience after long term bupe usage. I had the patch and took it as prescribed... 1 per week or something, I can't remember now, and I think they were .1mg... and the only way I found out they were literally doing close to 99% of nothing for me is when I ran out of them. I think I created that 1% of possible effect through pure placebo. I read that it helped "slow" people down, chill them out. So I wanted it to more than anything. But, I couldn't tell a bit of difference with or without the patch. Just my exp.
And, this is my opinion (from only my experiences), but while benzos seem like a life saver at the time... bupe W/D's are very long. I'm not going to argue intensity with anyone, but depending on what mg you hop off at, they can also be intense enough that you don't sleep and literally almost pass out from trying to walk. Point being, you may be trying to cover up the W/D's from bupe, with benzos, for an easy 2.5-3 weeks. And 2.5-3 weeks of any benzo, especially klon with it's long half life, or xanax because of it's potency, you will have W/D's from the benzos also, while the bupe W/D's are still going on, too. I hope I'm not coming off as negative, I'm really just trying to point out possible problems so you can decide for yourself how you want to deal with them.
