I know that we have had a lot of discussion about Timolol and the other combo meds and low blood pressure, but has anyone had problems with insomnia? I have been wracking my brains about what is causing this. It has been getting worse over the years and I have been on some version of Timolol for the past 9 years. I think it builds up in your system, but wondering if there is another alternative? I am also on Travatan Z once a night. I will certainly check with my doctor, but thought I would check with this community first. Thanks.
