That’s what I use...same effect too. 2 pills at onset, and then within an hour I’d be woosey enough to sleep a bit.
Even with that though, I generally feel like crap the rest of the day.
Last time I tried to refill it, I was told it is no longer available. No one makes it now because under newer FDA guidelines it doesn’t have proper approval for use and it’s too costly for the drug companies to gain necessary approval for continued sale.
