I have been taking Venlafaxine for many years and have never had a major problem with it. I have been coaching a co-ed minors soccer team. Every Saturday morning for the past month we have a had game. And, ever since I started the coaching, every Sunday morning I wake up severely lethargic, dizzy, lightheaded, headache and a overall feeling that my body is covered in lead. I sleep for many hours and it usually takes me til Monday night to fully recover. It gets worse everyweek. I have tried to stay hydrated, wear a hat and even applied sunscreen. No results. Is there something else I can do or not do? Please let me know what can be done. Thanks!
