I took my first dose of 50,000 units of vitamin (D2) this past Friday night. I was prescribed 50,000 units once a week for 12 weeks.

I experience adrenalin rush symptoms along with a little shakiness and insomnia. However once I fell asleep, I stayed asleep until I woke up abruptly feeling like I couldn't catch my breath and my heart pounding... I sat straight up in bed and violently coughed. It really scared me. After I calmed down all was fine and I was able to relax.

Now at 4 days later I just feel achy, a little nauseated, some stomach upset/cramps. I am finding myself a little scared to take the 2nd dose this friday night...

Has anyone had a similar experience? What can I expect after the 2nd dose? 3rd dose? etc.

Thanks so much for any advice you can give.
