My dad has been having stomach issues for I guess about 9 years now. Doctors and specialists have diagnosed him with cyclic vomiting syndrome. Over the years he's been prescribed a basket full of meds, with none giving any real relief, more of a bandaid to ride out the vomiting, pain and nausea. I've been thinking what if it's a parasite and that maybe he could benefit from trying Ivermectin. I've just recently told both mom and dad about it and think they are willing to try it. Just wanting some other opinions on it. Thanks.
