I recently went for blood work & found out that I have a very low amount of vitamin d in my system, it was on the lowest end of the spectrum. My Dr told me that it will help my immune system because I am always sick as well as help my bones due to a severe back injury I had a few years ago. I took my first dose last Sunday after dinner, I was told to take it after a meal. I am experiencing some odd effects & was wondering if this has happened to anyone else. I refuse to read the side effects on the pamphlet that comes along with a prescription unless I feel weird. So on that note I have been feeling the following: loss of appetite, extreme weight loss, now this really scares me because I struggle with anorexia nervosa. When force feeding myself my food is having a hard time going down as if my throat is swelling up. I'm so thirsty. I'm in the bathroom all day. I'm not sleeping at all & I take trazodone for sleep but it does nothing. I feel like a zombie. My bones & muscles are in extreme pain, I can't get comfortable. Dizziness. Blacking out upon standing. I'm sweating like a pig. I feel like i'm loosing my mind, over all confusion and forgetfulness. I'm really scared to take my 2nd dose this Sunday. I just don't feel right at all. Will these side effects subside? If so how long does it normally take? Should I be concerned at this point? Any information will be greatly appreciated especially if you have experienced anything like this. Thank you!
