I usually take 3 at a time because 1 or 2 do nothing at all to help but today I took 4 just to see how it would effect me and I'm terrified now I may have overdone it. I am dizzy and nauseas but for the most part that's all the symptoms I have. I also get the same feeling if I take my anxiety meds at the full dosage I'm suppose to take. So I cut those in half and I'm fine. My mouth is a bit numb and I am extremely relaxed. But still terrified I may have gone overboard.
