Jana, Your BP looks just fine. Not even a sign of over hydration or dehydration.
Green tea might cause more GI issues. So hold off until you've been thoroughly checked out! If it's alkaline, it might do more harm. Always try only one thing at a time or you won't know if it's helping or hurting.
Have you brought the "weaving" up to your neuro? Have you videotaped it? I think a neuro would be the one to run it by first, IMO.
With your migraine history . . . have you been looked at for any possible clotting disorders?
You have good doctors, so I'm sure they can help you figure this all out.
