I too suffered with real bad anxiety and nerves, wouldnt recognise me now but its been a long road to getting here.
I just started my dream job 3 weeks ago! I'm almost 50 too, life is only just beginning for me, been half dead most of my life, so many things wrong but never quite understood why until recently.
I have had the same problems with sleep, have had sleep tests in the past, and have been told I dont reach the level of deep sleep that is restorative!
I also suffer from extreme daytime sleepiness!
I am managing it better than I used but its still very difficult to live with, so I do understand.
by the way, I dont drink humanatea as a 'tea' I mix a bit up with some fruit juice and gulp it down in one go.
Once brewed, I keep it in the fridge and just swallow a small amount in cold juice, could drink it as is but not that brave...lol.
Hope all your cleansing go well.
