Vyvanse stopped working?

[caromango]

Diagnosed with adhd and prescribed Vyvanse ~2 months ago, gradually increased dose from 30mg to 60mg. 60mg worked well for about 1.5 weeks and now I don't feel like it does anything. I know that the upper dosing limit is recommended to be 70mg, but with how ineffective 60mg feels, I worry even the upper limit won't help. Why have I built up a tolerance so fast? What other medications should I ask my MD about that may offer me better symptom relief?
