These have worked lovely until tonight. Used one zaleplon, hour late still very awake so I take another. Another hours goes and then I take the 6.5 zolpidum... Been laying in bed trying to sleep since and it's not going well. Any suggestions? In the past they work fine (I use the zaleplon once a twice a week and have no problems... Only use zolpidium when zaleplon hasn't in the past.. So looking for advice and guidance. Thanks.
