Do not take this long term! I have taken it off and on for years but much more off than on. However for the past 3 years I got addicted to it at age 55. My personality has changed for the worse. I have suicidal thoughts and my grandson to me I look old now, but he still loves me. Also hair loss, intense insane anxiety, lost family and friends too. Please do not even start this. Oh and an autoimmune disease on top of it. I am lost.
