I took Adderall in college and it created more problems than it solved
What do you mean by this? Why did it create more problems than it solved? Can you tell me with details?
I was always tired and tried to sleep all the time
If you were taking Adderall in college it was probably for a good cause at first, but it might work differently on different people. If you get addicted to it then you need to stop cold turkey or get some help. Sleeping all the time is not good for making your grades.
I'll try my hand again but I will be going cold turkey if it has the same effects.
It is good that you are trying again. It is important to use all the tools that you can to succeed in college even if it is Adderall.
