Glendalegoon. If the pilot had been taking SSRIs (selective serotonin reuptake inhibitors), then a few days off them is certainly not enough. I've been on them now for ten years, and the UKCAA will not allow their use, so no licence. I once tried going "cold turkey", and ended up having a psychotic episode. They have to be reduced SLOWLY (i.e. over a period of months), and with doctors monitoring the effect. Ironically, while on them I function fine, but rules is rules.
