Answer: This depends on a lot of factors.You need to look at the ingredients in the sleeping aid and check them for reactions with alcohol or any other medication you might be taking. One excellent site is www.healthyhealing.com.I would recommend refraining from much alcohol use as it can contribute to your feelings of anxiety and agitation.Many herbs can be obtained in an extract (liquid) form either with alcohol as the agent or glycerine. You might want to investigate that option as well. I used CalmChild by Planetary Formulas when my children used to have trouble because they would get wound up once in a while.Other suggestions:Try and set as much of a routine as you can ... even if you travel on your holidays ... get up at the same time eat at the same time, go to sleep... try and stay as close to normal home as possible.Maybe incorporate a nighttime tea time into your routine. There are many herbal teas which can be calming. (stay away from black teas which contain caffeine if you have issues with caffeine). A nice cup of tea and a book or magazine can help relax your mind to let you drift away.Look into the possibility of a relaxation tape or CD you could bring with you. Test it out before you go.Investigate whether you MIGHT (keyword might) be able to use melatonin or 5-HTP to help. Lack of Serotonin can cause sleep issues.Get alot of physical movement -- walk, ride a bike, etc and be outside.Get sun (but stay protected).
