That is a normal reaction, and there really isn't anything out there to relieve that. Albuteral increases the blood flow therefore causes that kind of reaction in most people. I have used it most of my life, and sometimes I get the shakes and sometimes I don't, it just depends on how deep you breath it in. Don't worry, it won't hurt you, I just sit down and let my body relax and after about 20 mins I am fine again.
