Hello, I just overdose caffeine. I ve called the ambulance as I felt crumbs in my muscle and hyper, the operator said to check the blood pressure after one hour again [now it s 168/111. I have the machine at home]. Before I made the call I took a few pills of valeriane. I did not mension to the doctor about it. What is the effect of combinationhigh caffaine about 900mg and the sleeping pills? I did not eat much today, should I eat to lower the hypersness? thank you!
