I'm so sorry you're having issues with medications, I myself am on 8 different RX meds and I'm very on-the-ball with taking them so I don't think your behavior is "crazy" at all. I even carry my meds around with me if I'm out and about just to be sure.
I get my Savella through www.prescriptionhope.com and they do all the legwork for you to get you your medicines and it only costs like $18/month, which I'm guessing is lower than what you're paying now. I'd definitely recommend that site. Not only does it help me get Savella, but also Nucynta and Abilify. It's great because I was paying like at least $50 for each prescription.
You really shouldn't wean yourself off before talking to your prescribing doctor though, I wouldn't recommend it. You might be going through withdrawl too with all the symptoms you've been having.
I hope this was helpful to you! I hope you feel better!
