So perplexed: Just started Adderall, developing tolerance in days...

Started Adderall IR a few weeks ago. Here's my journey:

It seems that the first few days after I increase the dose I get really good effects, only for it to slowly settle back down to near baseline after some time.

Anyone know what is happening? Any help deeply appreciated.
