Please help..... I have recently started lamictal. I have finished the dose pack and jumped from the 100 dose to 200 the next week. I am feeling really crappy

. I have a bad headache, ringing in my ears, achy and am really tired. With all this going on I am not even sure it is helping my depression. I know that these are somewhat common side effects.........my question is HOW LONG WILL THIS LAST???? I have been taking the entire dose in the am and will try to split the dose this evening. Thanks for any help you can give me. I also take effexor xr 600, provigil 200 along with the lamictal in the am and clozaril 100-150 at night..thanks
