I started on the NR on the 11th of this month, the first week was pretty good just a little cramping(I chalked it up to having to get used to a new drug) on the 20th I started getting severe lower back pains I could barely stand to do my filing at work. the back pains have continued, I went camping this weekend & could not even enjoy my weekend with my daughter Saturday afternoon I started to experience a severe headache, nausea, light headedness, blurry vision, not to mention that I could barely open my eyes due to such pain from my headache. I was going to go home that night because I was feeling so horrible but I knew that I would not be able to drive for 1 1/2 hours feeling like this. I tried tylenol, ibuprofen, & even a percocet to try to relieve the pain. nothing worked. I decided to drive home on Sunday morning & on the way home I had to pull over to vomit twice & the headache just got worse. I decided to research the side effects a little more thouroghly since trying the NR was the only thing that I had changing in this time & never having such severe pains & headache before. I was shocked that a drug with some of the side effects is on the market. I have also had an experience with blood clots in the past & now I am getting worried about the aches that I have been experiencing in my legs & arms. I have taken the NR out tonight & I will let you know if things improve. I WOULD NEVER RECOMMEND THIS DRUG FOR ANYBODY!!!
