Has anyone felt at first such terrible feeling as I did? I felt fresh in first day but i do not really remember how the day was. I mostly was at home. I was calm but mood wasn't good. I really was confused and felt sometimes good, sometimes not good. Day two I was out with a friend and truly remember nothing. I had no appetite. I was very calm and very energetic but on the three day I was giving it up and couldn't take it. Should I keep taking it and wait a few more days?
