@WardrobeNightmares DD only suffered overwhelming anxiety, when she reached the full dose. DD was so anxious on Concerta, she collapsed before exams, until they gave her Propanol, and she’s also been prescribed Cyclizine, an anti-emetic iirc. However it’s like all these things, some people react differently, but the literature does recognise the stimulants can make anxiety worse. If we took the stimulants, they’d be like speed for us, whereas people with ADHD, it calms them down and helps concentration.
I gave “normal” DS phenergan once, to knock him out for an 8 hour flight as per the pharmacist’s advice - he was hyper and never stopped talking for 8 hours! It was exhausting!
DD has in the inattentive type ADHD, so behaviour was never a problem, except when it was driven by the emotional volatility, which was huge. The medication calms that down, until it starts wearing off in the evenings. DH clearly has ADHD, and is hyperactive, but he could always behave at school - however he spent all his free time as a child, playing football, so he probably wore himself out. As an adult though, it’s just exhausting to watch him! For me, the most relaxing part of holidays with him, is the flight home!
