Sometimes my ADHD meds give me anxiety, sometimes they don't. Does this mean they are not working? Same with caffeine although caffeine is more likely to cause anxiety than my vyvanse. Same when I take caffeine and vyvanse. Sometimes together they will cause anxiety, sometimes not. Also I take clonazepam. Is it odd to be prescribed an upper and a downer? I usually only take my clonazepam/klonopin a little after vyvanse peaks in the evening. About 6-8 hours later. Any thoughts?
