"ADHD" doesn't exist. Some say sugar is poison. A jew I used to have to interact with said it enough times. Some people are more active than others, and imbalances of Elements and Chakras not being aligned properly, and problems with the Soul and Aura... are problems which need to be fixed. If you was a kid, I might encourage to take you out to do something which can burn off all the extra energy. As an adult (assuming you are an adult) you can think of things to do, surely. An idea is to go to the gym or somewhere to exercise and tire yourself out, maybe kick shit into a punchbag or something...
You can use ISA safely if you use it for a specific White Magick purpose, and also state something similar to this - "In a safe, positive, happy manner for me". It's important to make the affirmation your own and add something like what I just said in the example.
For example - "In a safe; positive; healthy; and happy manner for me, the energies of ISA are causing me to be focussed and are helping me to concentrate when I need to..." - Again, make the affirmation your own, but also do add things like "In a safe and positive manner", as well.
Working on your Solar/666 Chakra is important, as well - it is the powerhouse of the Soul. All Chakras need to be worked on, as does your Soul and Aura. Psychologically, you should be prepared and ready and able to do workings, also. It might also be a good idea to use RAIDHO - "Reidh makes one aware of the natural rhythms in life and helps one to better organise their time."
Things take time, and can't be rushed. A full working is 40 days, and should not be started when the Moon is Void of Course. the 40-day working might need to be repeated, or you could do an 80 or 90-day working, instead of 40. You can also use sexual orgasm energy and SATANAS in your working.
