Awww I feel for you! They're HORRIBLE aren't they?! I had them constantly really badly until my Midwife put me onto Magnesium Tablets - After about 3 days of taking them my leg cramps were completely gone, has been about 10 weeks since my last screaming in pain 2am wake up call now! Has laos heard about he glass of milk & banana before bed for your calcium & potassium - Healthy habit to get into as well!! Good luck!! xox
