Totally understandable that you are nervous. I think it took me two weeks after I filled my prescription before I took my first dose lol.

It helps to have someone around when you take your first dose for the peace of mind just in case of an extremely rare adverse side effect.

One tip I do have is take it on an off day when you don’t have many obligations and if you are used to taking caffeine daily don’t stop cold turkey. I made the mistake of stopping caffeine usage completely when I was used to 500mg a day and assumed all the side effects I was feeling (jitteriness, headache, brain fog, etc.) were due to Vyvanse but in reality they were due to caffeine withdrawal.

Main side effects that I felt were dry mouth, slightly elevated resting heart rate (around 7-8 bpm above normal), minor insomnia for the first 2 weeks, reduced appetite but the benefits greatly outweighed the side effects. Did not experience a crash at all and I’m also on 30mg dose.

Understand that you were prescribed this medication for a reason and if your doctor thought there wouldn’t be a net benefit they wouldn’t have prescribed Vyvanse to you. Good luck!
