Lows and newly dx'd and starting insulin

Ok, so we started humalog today. (We = me then nut RN Mom and my 20 year old type 1 diagnosed about 2 and half weeks ago.) She woke up this am at 210. Ok I want t o try and start this slow so I can see how it affects her. Ate breakfast (really lunch bc thats when she got up) and after 2 hours was at 325. Called endo....got scolded. Ok so now its supper prior to eating she was 180. Two units had chicken fingers and french fries and two hourse later she felt weird. 71. Juice box and in her panic was shoving chips in her mouth too (Again, first time.......didnt kowhow quickly anythgin would work) 15 later she was at 123 and feeling better now at about 180. Too high still I know but i think it ws teh chips and the juice??? My question.......after you drop and come up........will it go back down? I know the humalog is supposed to be short acting so shoud be done by 10(now)??? I gave it at 6. 

They also wanted me to start lantus at bed....Im freaked now and so is she, so I am pretty sure thats out for tonight. I will call AGAIN tom and get yelled at Im sure but I was so worried about a low and sure enough after No response this am at 1 unit,,,,,,this happened the very next time with 2??? UGH........
