High discharge 18650s can provide 20-30 amps, doubt the lamp needs that much current if it’s powered off older battery tech

That’s fair

Doctors can prescribe up to 70mg doses of Elvanse, so you shouldn’t overdose. If necessary seek medical attention, but most likely you’ll just notice it come on much more since you still seem to be trying to find the right dose for you. If you weren’t noticing anything on 30mg then you might see some positive effects at 60mg, but you should work with your doctor to find the right dose for you, taking more than prescribed once is a mistake, doing it regularly might be seen as abuse of a controlled drug.

If you wanted to try to make your original rubber band idea work, you could try moving the central dart up slightly so that the rubber band forms a triangle shape and adjust the contact points between the rubber band and the darts to be at each corner of that triangle

I went through Psychiatry UK for mine and they were fine, although from your link it seems they are currently one of the longer waiting lists, so I would suggest trying someone else with decent reviews. I didn’t need to wait long (maybe a week) for my referral to be confirmed, unlike the other person in this thread.
I would suggest making sure that the provider is a yes on the “Authorised to provide NHS ADHD Medication Prescriptions”. You can sign up for an NHS pre-pay certificate once you are getting regular prescriptions to save on the prescription payment.
