It can be addictive, psychologically, because it is taking away your anxiety, insomnia and even your hppd symptoms. Feeling like shit, or feeling almost normal, which sounds better?
It is also physiologically addictive. Your brain gets used to those chemicals in your blood and the receptors begin to require them, if tolerance builds, they require more and more.
If you can do the 3 day on, 4 day off routine, like I do... You might be able to do it for life. I've experimented with 4 days on, 3 days off too and it seems fine, though I am a little nervous about doing that long term.
I am trying this for 3 months:
Thursday 6pm - 0.75 mg Klono
Friday 8am - 1 mg Klono
Saturday 8 am- 1mg Klono
Sunday 8am - 2.5mg Lorazepam
By taking the Sunday dose early with a faster half life benzo... then taking the Thursday dose later in the evening... I still give my body a good window to clear itself and for the receptors to recover.
Once the 3 months are up... I will go benzo free for 2 weeks to monitor any addiction/tolerance build up. Currently, I feel no different during the off days as when I was on the 3 on, 4 off routine.
