Taking stimulants will most likely not cause you to breathe more frequently, but constrict your lungs causing you to lose oxygen. This will raise your heart rate causing extreme confusion/unconsciousness while your CNS (central nervous system) is so depressed. This is going to cause many problems and possibly kill you. Before trying adderall or caffiene, I would try nicotine, but that will also cause many other health issues.
You need to stop drinking. I went through alcohol withdrawal about a year ago and I feel your pain and fear. You may go to the hospital where they can help you through it. With there help, it won't be nearly as bad. I know from experience. I tried it alone and had hallucinations and other symptoms for a few days. It is extremely unsafe to do alone as I could've died from a heart issue or seizure. If you can't afford a hospital/detox center, you can try weaning yourself off alcohol. I tried this too and it worked but it very hard to do because you have trouble controlling your urge to drink. If you only drink enough to ease the heavy symptoms of withdrawal and nothing more, you will slowly bring the drinking down. Using benzos as a substitute for drinking when in withdrawal helps b/c as it is the same as alcohol in pill form, so your addiction will not go away. There are many ways you can die other than Respiratory depression when mixing alcohol with these drugs, and thats not including the physical illness you will cause in your body that will also play a role (diabetes, heart palpitations, etc.). Please find help.
