I joined a workout program which runs from 6.30-7.30 AM 3 times a week. It is high intensity. After class is done I take a shower and then finish my kitchen work for an hour. Now the problem is I'm extremely tired while doing kitchen work. Around 1pm I literally crash into bed for an 30 min nap. But after this nap time I generally regain all the energy . On days I don't exercise I don't have this problem . I'm wondering if there is anything I can do to overcome this tiredness. I checked with my instructor and she suggested a protein drink. Unfortunately I get constipated with the milk protein and I don't like vegan protein powder. I'm not a breakfast person. I have tried drinking green tea/ coffee but nothing can stop this need to sleep. Any suggestions ?
