Mum came back from her recent holiday much perkier than she had been for a long while. However, when I visited earlier this week, I realised she hadn't been taking her prescribed medication regularly. In fact, it seems that she's missing her evening tablets quite often. While I've been staying - over the last 4 days, I've been making sure she's taking all her tablets, but she's gone back to her pre-holiday self. Basically, she's back to being tired all the time, with no sparkle and no appetite. She takes metformin in both the morning and evening, so I don't think that will be the problem, there's aspirin in the evening, too, but there's also simvastatin. Could it be the statin that's causing a problem?
