Mild Morning Sickness?

Is it possible to have just a mild case of morning...well...really it's all day...sickness? Last week I had the beginnings of what I thought were going to be a miserable few weeks....but now this week I'm not feeling quite as bad. I'm still extremly tired...exhausted really....and get mild waves of nausea, but nothing like last Friday was. I'm hoping this is the worst of it...and that it will be tolerable the next few weeks. I can't believe I'm closing in on 8 weeks already. We have our first doc appointment next Friday, so just really looking forward to that!! :)
