Thanks all.
So this week the withdrawal symptoms have been easier which is a good sign. I have decided to do a headache diary and document type of headache I am getting. How many times a day I am taking ibroprofen or paracetamol and any other symptoms. My headaches and fatigue are getting me down but I am pushing through it and trying my best to get on as normal as possible. My manager is very supportive and I explained that I have currently lowered my ad dosage. The thing is I am not going to know if the headaches and fatigue are symptoms of venalfaxine until I am completely off them. I have a feeling it's going to take me years to come off them. I am also on preglabin and not coming off that. Who knows. But a diary is a good way forward
