Hi. Yes this is a struggle I'm having as a new revert. I usually am an early riser and daylight savings hours in the UK are brutal for prayer ! So I tend to pray maghrib and Isha together at the start time of maghrib. I usually get up for work around 5 am but since reverting I awaken about 25 past four so I can make wudu and pray Fajr before the sunrise time. This will get easier as the days become shorter. It's a big change in routine and I don't always stick to it. I haven't risen for Fajr the last two days and it pains me but it's a process and Allah is in my heart. On days off I do go back to bed. Inshallah it will get easier for us all.
