Verapamil Hydrochloride and drugs

I was put on Verapamil 120mg after being taken off of Atenolol which I had been on for 5 years. I also took Lisinipril along with the Atenolol. I had a couple of rough months getting off the Atenolol as there are some side effects to doing that. I was put on th Verapamil along with Enalapril and Hydrochlorithiazide, didn't feel well. Off the Enalapril and Hydrochlorithiazide now and have increased the Verapamil to 180mg. I feel so tired but can't sleep, have no energy and my heartrate is still up there. Doctor wants to add Digoxin, will this help or make it worse. I felt better on the lower dose but it wasn't controlling the BP.
Thank you for your time and would appreciate any info.

Several months ago my dr prescribed verapamil and quinapril to control my high blood pressure. My diet is the same as before taking these medications, but my cholesterol and triglycerides are much higher now. Total cholesterol has gone from 168 to 217. This may not be related to the drugs, but my cholesterol level has been fairly constant for several years.
