2. Rethink Your Diet
Reduce carbohydrates. Evidence suggests that the consumption of simple carbohydrates may elevate mood temporarily, but that overeating carbohydrates then leads to fatigue and depression. One can achieve a more permanent control of their mood by eliminating simple carbohydrates from their diet: for instance, by avoiding candy, table sugar, packaged cereals and cake.
Eat smaller, frequent meals, giving favor to complex carbohydrates (such as pasta and whole wheat bread) and protein.
Eliminate caffeine products (such as coffee, tea, and some sodas). Caffeine may affect mood in women with PMS as it is absorbed slowly, so the caffeine ingested has a lasting effect.
Avoid alcohol. Women with PMS have been shown to drink significantly more alcohol overall.
Wrong diet along with emotional stress and worry can also cause sleep related problems during PMS. Foods like bananas and cherries contain tryptophan, potassium and magnesium which are muscle relaxants and thus good for sleep if taken 30 minutes before bedtime.
