I've been using 2mg klonopin at night for 1 week but the last few days it seems to have stopped working or giving me a completely different outcome when using it. The first week i got at least 8 hours sleep while using it and as a very nice side effect it alleviated my brain fog somewhat due to it's neuroprotective mechanism?. I felt calmer during the day, quite "normal" so this drug was a big "wow" for me. 2mg now just doesn't do anything or keeps me awake instead of sending me off into deep sleep. I tried 0.5mg last night, a lower dose gives me a very mild sedative effect but i wake up after a few hours and have to take xanax to get back to sleep. So what's going on? Are my receptors already satiated? Does a lower dose versus a higher dose give a completely different effect after X time, just like with LDN (low dose naltrexone?) I can use another sleep agent but i prefer klonopin for it's neuroprotective mechanism and the fact that it made me feel more "normal" the first week.
