Sydney, sorry to hear of your father having a difficult time. The slow change of medication is always best, so I suspect a bit of a shock to his system. I do minor things and it seems it takes two to four weeks to be back to normal.

When I had a PET scan they said, "remain still for 45 minutes". Uh, not possible. I have a dislike of tight spaces, which causes stress, and I shake life crazy. So the good Doctor gave me 2mg of Xanax. I'm not a small person but have dropped from 21 to 19 stone over the past year. For those in North America, a stone is 14 pounds. So close from 294# to under 266#.

Still I was out for 45 minutes, but an hour later back to my old self. Worked like a charm.

Best wishes for your father.
