I started out on vyvanse, and had headaches if I got at all dehydrated also. I loved it as a med, but I think I just loved the feeling of focus and relative normalcy. I didn’t really have euphoria with it. I did get a tolerance for it quickly though, and finally decided it wasn’t for me, even with a low dose booster for the afternoon.
I’m on adderall now, and I think it is superior for my body. I take an xr then an ir in the afternoon for breakthrough symptoms. Again, no euphoria, and no real noticeable side effects otherwise either.
Ritalin works great for many people’s physiology, but it’s definitely not the only medication out there. The newer ones tend to have less side effects, but that’s not a rule.
