Me and my girlfriend bought the stress & anxiety day and night formula yesterday. We both tried 1 tablet of the night and we both woke up the next morning feeling really bad. In fact she had nightmares the whole night that were really weird feeling and I woke up this morning feeling like my kidneys and liver was damaged and really sore. About a half an hour after I took the pill last night I felt both the left and right sides of my abdomen twitching. I couldn't sleep for like 2 hours because I was more awake after I took the pill. My girlfriend isn't taking anything except birth control by (YAZ) so there is no excuse for it not to work for her. For me, I'm not sure if it would have done that to me anyway, but I took a ultimate liver cleanse tablet by puranol the same day and also a glucosamine/chondroitin/msm tablet by spring valley for joint health. I took both these at least 8 hours before I took the pill from natrol. We did not like this product and kept us up while making us more stressed the next day.
SAF Stress & Anxiety Formula is great! If I am really stressed out, start freaking out about life, or in a really bad mood, I take 3 or 4. Half an hour later, I feel much better. I don't take it every day, just when I feel stressed out. It really helps.
