Pro sleep and anti depression
After several emotional blows I found myself dealing with depression. Unable to sleep, unable to get out of bed, needing to force myself to do needful and necessary things. I was taking Sam-e already, (which I highly recommend, but it was insufficient) and I added Siddha remedies in addition to upping ny Vitamin D and taking 4-6 of these daily. I also started walking, journaling, and committed myself to working a plan to get out of the depths. This Trytophan was definitely a key player. I want to highly recommend therapy as well because an all around approach is necessary. Thorne vitamins and minerals are excellent too. My regimen included 2 tryptophan and 3mg time release melatonin from life extension an hour before sleep, and two more with Siddha Sleep and magnesium at bedtime. Upon a too early morning taking I sometimes take two more. The difference is absolutely profound. I use several of the Siddha remedies throughout the day, but again this is key. My sleep quality is stellar and I actually awaken refreshed. Five stars
