Weird and possibly dangerous symptoms

[nonnu]

I started vaping about 3 weeks ago. This tuesday I was lying on my bed and took three hits from my Aspire BDC + eGo battery. It had Alter Smoke's vanilla and café, 11 mg nicotine and 80/20 pg-vg-ratio. Suddenly I began to felt dizziness and my body started shaking. The shaking ended in 40 minutes but I was very dizzy on the next day too. At first I thought that it might be a nicotine overdose, my clearomizer has spill some liquid in my mouth before and it might be the reason this time too. But. Nicotine overdoses shouldn't last so long as the half-life of nicotine is something like two hours...

So I went to doctor. She asked me a lot of questions and made some tests and she said she's pretty sure that the dizziness is caused by too tight neck muscles. I was very stressed before the symptoms appeared and it quite didn't help with it and I tend to have problems with the back of my neck when I'm stressed. She gave me muscle relaxant injection and it made me feel better.

Thursday was better, though I didn't feel as normal as I should but it didn't bother me. Yesterday was even better.

A couple of hours ago I took one hit. The dizziness came back, though no shaking this time. My throat feels kind of weird, like I had some food stuck there or something.

What the hell is this? I'm scared. And, sorry for my bad English.
