I was prescribed lemberoxant for sleep problems due to insomnia . Now doctor said to stop and see how it feels. I stopped but after two days i started taking ashwagandha thought to help me stabilize but never hit the thought that lemberoxant might interact with ashwagandha . I don't have any specific symptoms of interaction but scared to death that they might cause some internal problems , i can't get it out of my mind at all . Plus to that my vitamin d level came back as 45 ng / ml . I thought I should boost vitamin d so took one 60000iu tablet , without researching anything . I am having massive fear of this all together causing harm . I do seem to have a little discomfort in my stomach don't know if is caused by stress or this potential overdose or interaction .
