Methods for Quitting

So this will be a lengthy one. I'm a long winded person lol. Anyways I've been hooked on Feel Frees for about a year and a half give or take. It's draining my finances and I'm worried about my health. I average about 7 a day. But the past few days I've been doing 8-8.5. I have some ideas for how to quit and want to run them by you all and also hear ideas from you guys.

My first idea is to get prescribed vyvanse, which I used to take so could easily get back. They both pump your brain with dopamine and make you feel good so I figured it would help a lot considering it's cheaper and easier to quit than feel free. To any of y'all's knowledge would a feel free or a few interact bad with the Vyvanase? And I'm talking like death or seizure or heart attack kinda consequences. If it causes anxiety or irritability I'm cool with that. Just don't wanna damage myself terribly or lose my life. Both pump you with feel good chemicals right? So maybe that's offset some withdrawals and I could take less FF.

That is honestly my main go to idea. Obviously I can taper off but it's so unbelievably hard to stop once I get one in my system. Another thought I had was using powder kratom to get off. But it doesn't seem to be working for me. I went to Thailand last year for 10 days, was withdrawaling hard on the way and on the way back considering it's as 24 hour trip. But when I got there and bought kratom, my withdrawals went away completely. Didn't even think about FF the whole time I was there. Not sure if it was because I knew I couldn't get them, or because the kratom there is much higher quality than the powder stuff here. Or a combination of the two.

Also something that helped me get through the withdrawals on the trip to get to Thailand was coffee in case none of y'all have tried that. Idk why but coffee made them more tolerable and honestly I need to start implementing that again to reduce how many I take a day. I really don't want to keep being broke and asking people for money, or even worse do irreversible harm to myself. Please help if you have any other effective methods and have any knowledge on the interaction of vyvanse (ADHD meds) and kratom/kava, specifically feel frees. Thanks if you read this far🙏
