I've been diagnosed with ADD since I was a child, but never liked taking my medications because I always felt kind of weird on them. So I've always kind of tried to take them sparingly. I've been on vyvanse (30mg) for almost 5 years now, but only took it when I felt I really needed it (sometimes a 30 pill prescription would last me upwards of 6 months). However I am now a Junior in college, in a rigorous degree program, and am find it harder and harder to go with out taking it especially around midterms and finals. I've never taken it more 2-days consecutively, is there any risk in this? What about if I pull an "all-nighter", is there any danger in taking my pill in the next morning? Any help is greatly appreciated.
