I have being diagnosed with adhd used to take inspiral 10 mg 3 times, but later due cost of frequent visit to phycatrisit for refill and anxiety issues I stopped taking. Now since I am writing few professional exams again I'm unable to focus well, I used to take modalert before inspiral it was cost effective but not as good as inspiral. Now considering cost and dosage requirements, can switch to modalert. Ps. I lost my job in between when I stopped due inattentiveness. Joined a new place which understand my rhythm of work.
