Take Phyllocontin tablet, morning and night. Last night I had tremendous cramping of legs and toes. Lasted about three hours. Every time I thought oh good it's away, it came back. Know you're not supposed to have alcohol with theophylline but surely two wee bottles can't have caused it? Rarely have a drink but it was so warm last night and for once, I didn't have an early school run to do. I did have glass of water before going to bed. Any thoughts? I'm on Relvar Elliptiss and Metformin ER too.
