*UPDATE:
I'm FINALLY seeing an improvement. I think I just had many of the side effects from the Zoloft. I looked up all the side effects and I got about 70-80% of them. As of today (Aug. 27, 2019) I haven't needed the Vistaril in 4 days which is a major improvement. It looks like the side effects are subsiding. I have been keeping a very detailed daily journal so I can read back an see if anything changes. Sometimes the change is so subtle that it's hard to recognize, the journal has helped me greatly! One thing I noticed and I want to share it for everyone's benefit... When I eat bread, rice, or pasta my anxiety was through the roof within about 5 hours. I'm not gluten intolerant, therefore I hadn't made the connection earlier. The same happened when I ate sweets. I'm now eating protein and fruits and I have to say that I see the difference not only in my anxiety levels but also in the shakiness that I had every day.

I guess the bottom line is that we have to give the medicine time, try to figure out patterns (journal) to see if we're experiencing side effects, and wait for the side effects to go away. I'm glad I waited.
