Vegas Hangover Or Spring Fever?

Gosh since we got back early Tuesday morning from Vegas, I have been WORN OUT! Tuesday waking up was a given, I thought I might make it to Trekking class, but no way! I felt like I was in a daze most of the morning, but thought I might catch at Kickboxing class that night...but nope! Decided to be lazy. Wednesday morning I would be fine I thought. Well my alarm went off at 6:30am for my track workout and I thought I might 'just close my eyes', well that lasted until 7:45. I missed my track workout that I love to go to. So I rushed in my slow motioness and made it to 9am kickboxing, but barely could do much there, I was just so darn sleepy. I am taking Claritin, but it takes a while to kick in. Everything is blooming and its doing everything to mess with my allergies I guess. I did make it at my normal time for Bootcamp this morning, but still felt a little sluggish. I need to catch up so I can be my normal 'full' of energy self! We barely slept in Vegas, and surely I am caught up..no??...
