I’ve just been prescribed Fostair and am struggling with a few things. I have a very sore mouth despite rinsing after every use. Also my anxiety has worsened and I’m unable to sleep. Has anyone else had this experience? I’ve also read that you can’t drink alcohol whilst on it. 1 pharmacist said not too whilst another said there would be no problem so I’m confused. I only have alcohol every now and again. What’s people’s experience of this please.
