The fluctuations are from a combination of the Met and food. The Met will lower your glucose levels because that's what it's designed to do. Readings after eating meals, especially high carb ones like Malt-o-Meal, will raise your glucose levels. Going up to 183 is not out of line for right after a high carb meal. Plus with eating sugars you'll get a quick rise in glucose with a crash later, which could be why your levels are going down into the 50's. Your post did not indicate any exercise, but that will also make your levels go lower.
The idea is to keep your levels between 70 and 140, which can be done by balancing your protein with complex carbs. Cut out white starches like potatoes, pasta, white rice, table sugar, junk food, etc. Substituting whole wheat pasta and brown rice will help. A good book to help with this is The Insulin-Resistance Diet by Cheryle R Hart MD and Mary Kay Grossman RD.
Hang in there, it does get better!
