i tried this for less a month. a first it worked great, but after about a week i started upping the dosage slightly by just taking a little powder out of another capsule. i just kept increasing the dosage every few days to avoid the crash feeling. there was a few instances that it was wearing off and i felt extreme anger. overall, it made me a danger, and i discontinued after about 3 weeks.

I have been taking Vyvanse since Nov. 29th. I started with 50mg dosage and beginning next week will be taking 70mg. My Dr upped my dosage because I felt the same problem with the 'crash feeling'. She believes by increasing the dose that I will not drop out as soon. I hope she is right.

I can relate to the extreme anger. When the med wears off, I have this intense feeling of rage and the slightest things make me feel like flying off the handle. Sometimes I can talk my way out of exploding, but at other times I turn into a villain.

However, I have improved in other areas and thus far feel like the advantages outweigh the disadvantages. I can focus on tasks much better than before. My reading and comprehension has improved.
