If I could go back and really think about a career, I would consider the ASN to RN life. However, that being said, my wife did it and theres a reason she only works in the OR or OB/GYN/Labor and Delivery. Not to mention, the programs are demanding as hell. I coasted my way through BS Fin and MBA and I'm doing just fine. Also, it is a reality that community college ASN programs are extremely selective, demanding, and competitive.
Back on topic tho, my wife is wrapping up her BSN right now (3 weeks left, thank god, no more additional student loans EVER!) and yes, it would be best for you to get your BSN as it opens a lot of different openings and you will most likely be required to get one anyways. But let the employer pay, unfortunately, I had to pay.
That being said $70k is stellar for ASN right out of college with no experience. I assume you are working graveyards and that has built in overtime. RN pay in TX is $28 an hour. Tough gig, don't get burnt out.
Also, don't get drugs because you are lazy. I would think someone with your background, you would understand not to toy with them unless its a medical necessity. For example, someone taking ADHD medicine who does not really have a problem can cause big time side effects.
