I don't have sleep even for a minute since last 5 days. If I fell asleep, nerves in my head vibrating and I'm suddenly coming out of sleep and it's happening whenever I try to sleep. This was started 5 days ago, someone known to me visited me and we had dinner together. I strongly believe that this person is medicating me secretly as I had pain under my left rib cage (when I breathe deeply) last month, when I had dinner with him and I have been in medication till last week and he again met me and did this to me. What is the test I need to get it done in order to find out what kind of medicine he is giving me? And where that test is done? Please help me with right details. Thank you.
