Thanks Mrs D., the thiamine is in the 5HTP. That's what my doctor told me to buy. I scan ussually eat red & green peppers so I don't know if the cayenne supplements will bother me but thanks for that tip. I started tart cherry juice before I went to bed last. I couldn't sleep because I got anxious. I don't usually have anxiety however I do have a family member I'm worrying about. Have you ever heard of cherry juice causing anxiety? I'm using it full strength. Two tablespoons. Do you think I should mix it with some water?
