You are not obligated to give up anything during Lent unless you want to. You are obligated to fast on Wed. and Good Friday unless you have health issues or past the age of obligation…say 65. To fast you eat one reg. meal and two smaller meals. These should be meatless, but you can have fish, eggs sea food.
For Lent try to give up bad habits or take on new, better habits-a change of life style. We do this as a sharing of the Lord’s penance of forty days in the desert and as a memorial to His crucfiction. When Lent is “over” it is not a time to go back to our old ways, but an opportunity to take up new ways and “carry the cross.”
The Stations of the Cross and adoration before the Blessed Sacrament are a couple of things you can do should you have the opportunity. Hope this helps.
P.S. I am not “new” here 'though it looks like it. I had to re-register and create a new page due to some tech. problems.
