Soma , I think is a powerful sleeping pill ??? Not really sure ....
Vicodin is a pain pill , which is highly addictive , & gives energy for people in severe pain.
Adderall I think is an antidepressant drug , or is used for ADHD disorder ( the Hyper Kid Drug ) & Similar to Ritalin ????
I think Vicodin is just above ibuprofen on effective pain pill,....wife was fighting bone cancer and it did very little,...had to use Lorcet and then oxycontin, which didn't really do that much,...then we moved on to more effective stuff....
