Sores in the mouth symptoms and conditions

After taking 5-750 mg pills I began to lose taste, had very dry mouth while sleeping which woke me up. some sores in the mouth which i attribute to the pills too. Now, 10 days since ending the pills I still have some taste problems and dry mouth in sleep

I was put on 40mg per day of Prednisone for a sinus infection. I felt good for 4 days, then very weak and tired with headache and nausea. The doctor did not prescribe tapering off, just stop after 10 days. I quit after 9 days. Horrible withdrawal, very weak, bad headache, terrible nausea. My blood pressure dropped from 120/80 to 96/40. I had been on 25mg Lisinipril and Hydrochlorothyazide - doctor stopped that. Blood pressure now 104/60. Still very tired. Headaches almost gone, nausea gone. Complete blood panel tests all normal. Dr says symptoms will go away. It has been 3 weeks since I stopped the drug. Some fluid retention, but that is going away. Has anyone experienced LOW blood pressure with Prednisone?

Overall I'm feeling much more positive, capable of doing things, better emotional assessment and judgement. One side effect, though, is my breathing. I feel a slight tightness in my chest, almost light wheezing, but not exactly, and I feel like I've got to cough lightly to clear my air passage. Has anyone experienced this? Any insights are appreciated.
