And vyvanse, I believe, is not a med that one has to take for awhile before it starts working. So, you do need
to talk
to your doctor
to let him know what is going on. Oh, the med is fairly fast acting, so you should be seeing the results.
One thing that does bother me though is that this is information that your doctor should also have given you. Hopefully, he/she is not being remiss in other areas of information. Medication is only part of an overall treatment program.
