For an immediate remedy for lack of sleep you may take one teaspoonful of benadryl ( cough syrup ) which is available over the counter but make sure to contact your psychiatrist and ask him to add a sleep aid drug like klonopin ( clonazepam ) at dose of 0.5-1 mg to be taken on PRN basis that is as and when required basis.
Also you shall ask your doctor to revise the dose of lamictal , as a further increase in the dose to 300 mg to be done and that is to be taken in 2 divided doses for managing your racing thoughts and other symptoms of impending mania or else addition of another mood stabilizer such as valproate at dose of 300-500 mg twice a day shall be considered to potentate the efficacy of the current drug regime which seems to be getting ineffective as days pass by thereby threatening the onset of a manic episode.
So to summarize..
-- As a quick fix use benadryl on PRN basis for bringing in restful night time sleep..
-- Ask your psychiatrist to prescribe klonopin or xanax as a sleep aid drug at night to be taken on PRN basis..
--Also ask for drug regime revision by either titrating up the dose of lamictal to 300 mg and taking it in two divided doses or adding another mood stabilizer such as valproate to bring mood stability.
