Takes so long symptoms and conditions

I had been taking lisinopril for a few years with no apparent effects but last summer began waking with extreme fatigue and slight nausea. I also developed spiking blood pressure but that was stopped by adding a beta blocker. I have vivid dreams and often wake feeling worn out from the dreams.The fatigue is severe and accompanied by depression and anxiety. I also wake feeling hot in face and torso and have intolerance for heat.My dose is 40 mg and has controlled my BP until recently when I have had a couple high readings, possibly due to anxiety. I also had a couple of remissions when I felt OK fro a coule weeks, but the symptoms recurred..

I have MS and the first high dose steroid treatment (Prednisone) I was on I weighed 115lbs. I just finished my third high dose treatment over the last 2.5 years and now weigh 170lbs. I'm sure this wont be my last treatment either. The other bad side effect is it seems to kill your taste buds and it takes so long for them to go back to normal.
