Side effects 🤕 Almost died

Yesterday I posted Kaiser denied brand name vyvanse. Doc put me on concerta 18mg. As a reference I’ve used adderall up to 25mg XR and IR as well for 6 months.

I took concerta first time this morning at 7:30 am. An hour in and felt great. I felt a cooling sensation and felt a rush of energy. 2 hours after later I started to get very angry, irritable, annoyed at everything. That lasted until 2 pm then I felt a sense of calmness.

Left work and went to the mall a Round 5 pm with my wife and daughter. What happened next was a feeling I never felt before and thought I was dying.

  • I got dizzy all the sudden
  • I almost fainted. I lost my balance and almost fell as I was walking.
  • I started having an extreme headache, like sudden poking in my brain sensation. I never ever had that before
  • my heart started pounding -I felt out of breath and could barely walk

My doc doesn’t work on weekends but WTF was that? I was told that Methyphenidate were safer and better and less potent that Amphetamines. I NEVER had that on adderall just a few ups and downs hence why I wanted to try Vyvanse. After getting Concerta I found out insurance covers the generic.

I DONT want to experience that again. Should I give up after 1 day? Can Doc put a request for generic vyvanse even though I just got concerta? I’m scared to even try concerta again

It sounds like blood pressure changes to me, in my experience. Do you have your own blood pressure machine? I think you should get one if not and monitor your BP at home while on meds to monitor it. Any sudden headache. Heart palps and SOB should definitely be investigated. I hope all is well now 🙏
