Marty what makes you not get tested for gluten? It could really give you some direction. I can imagine it would be hard to keep this type of diet but if you have gluten intolerance and you even eat a little it can cause health issues. Your gp or any doc can at least be a starting point and run bloodwork. Marty are you on any meds?
Hope I am sorry you have been feeling down. it can be hard to stick to a health path when that happens. I know depression are you seeing anyone for that? You may want to as it may assist in everything. If you want an email buddy I am here too.
