Hello side effects

Yesterday was day 4 of the Lupron injections and up until then I had not experienced any side effects of this drug.  Not so anymore.  Last night I felt like someone punched me in the stomach.  And when I stand up everything starts to spin a little, which isn't good since I already have bad balance. haha  I can fall over just standing up normally so this could be pretty embarrassing.  Oh well.  The only other side effect is that I haven't been sleeping well.  At all.  I didn't realize until now that trouble sleeping was a side effect and I've been experiencing that since I started the injections on Friday.  At least I haven't had any hot flashes yet!  And at least I've only felt nauseous and haven't actually throw up.  It could definitely be worse!  Hey, maybe since I feel sick I'll eat less and then I'll lose weight (:  There's a light at the end of this tunnel, haha
