It took me two years to taper off of 2 mg clonazepam. Terribly addictive drug but WOW does it work well! It has been associated with dementia with long term use. Now I only use .25 alprazolam if needed if I wake up in the middle of the night. I even worry about that! I use 10 mg THC along with 300 gaba and a low dose naltrexone at bedtime. Check out the benefits of LDN. It's amazing. The THC is medical. It works well. It does not have long term detrimental effects that have been noted. I use a tincture and do not inhale it. The antihistamine usage for sleep is also associated with developing dementia.
